How long can you wear without removing contact lenses? How long can you wear lenses and why can’t you wear them over? Is it possible to wear contact lenses without removing them?

Contact lenses are a popular, convenient method of permanent vision correction for people different years. They are absolutely safe, but keeping them on your eyes for too long can lead to problems such as allergies, infections and inflammation. Therefore, you need to know how much you can wear contact lenses different types without taking it off to protect yourself from diseases.

Types of lenses

When purchasing contact correction products for the first time, you should consult an ophthalmologist. He will determine the optimal model for the patient and give basic recommendations for processing and use. The main models are proposed in the table:

View	Peculiarities	Term of use
Classic	Models are affordable, but require constant expensive care using special solutions and tablets against bacteria	6 to 9 months
Quarterly	Not popular, almost never used	3 months
Planned replacement models	Made from hydrogel or silicone hydrogel, a disinfectant solution is sufficient for high-quality care	1 month
Weekly replacement models	Thanks to the special material from which they are made, they do not require cleaning and do not cause eye irritation.	The wearing period should not exceed 7-14 days (in rare cases)
One-day models	Expensive models, of high quality, do not cause inflammatory diseases before our eyes	1 day

If the lens is made of soft material, on average it is allowed to wear it without removing it for up to 12 hours a day, and when it is hard - no more than 10 hours.

Colored lenses can be used both to correct vision and to change a person’s image, giving a different color to the iris.

Colored lenses have gained particular popularity. They allow not only to correct vision defects, but also to transform appearance person, change their image. Such products are made from hydrogel and silicone hydrogel materials High Quality, which allows them to pass a sufficient amount of oxygen to the tissues of the cornea and moisturize the eye. However, due to the softness and coloring matter, the oxygen permeability of these models is less than that of transparent ones. Therefore, you can wear colored lenses only in daytime and not use them for a long time - up to 4 hours.

How long can I wear it without taking it off?

The wearing period depends on the type. The packaging always indicates the rules that should be followed. There are models that you can leave on at night, although doctors still recommend refraining from sleeping in them. There are 3 groups based on the possible duration of continuous use:

• Daytime wear: be sure to remove before going to bed, walking with them in front of your eyes is allowed for a maximum of 14 hours.
• Long-term wear: you can leave it on for a week.
• Continuous wear: allowed to be worn for 30 days.

It is better to buy lenses that you can wear without removing them as little as possible. Significantly fewer eggs are collected on them than on those that are left in front of your eyes for a month. The wearing period is influenced by the manufacturing method, thickness, percentage of moisture content, individual tolerance and other factors. Big mistake- do not remove the lenses if you suddenly experience a burning sensation, itching, blurred vision or other discomfort.

Wearing rules

To use the optics for the entire recommended wearing period, you must follow the rules of care and disinfection.

For safe and comfortable use, you need to clean, rinse and disinfect your lenses. Cleaning and rinsing help remove stains from wear, while disinfection helps remove germs that are harmful to the eyes. Used for cleaning soft models disinfectants. For effective care, you should follow the following sequence of actions:

1. Wash your hands with soap.
2. Fill the lens container with the solution.
3. Remove the corrective optics and pour a couple of drops of liquid onto it.
4. Rub the surface of the lens with your finger and rinse.
5. Place it in a container and fill it completely with solution.
6. Leave the lens in a tightly closed container for a while to disinfect.
7. After each use, the container is rinsed with liquid from the bottle and dried. This solution lasts for 2-3 months, then it is replaced.

A large number of SCLs (soft contact lenses) are designed for daily use, but if necessary, some of them can be worn continuously. Whether it is possible to leave the lenses on at night and the duration of wearing depends on the type of contact correction product.

There are several types of lenses:

• Daytime wear - they can be worn no more than 12-14 hours a day. They cannot be used longer or continuously, since their composition is less moist than contact correction products for long-term use. If the rules of use are neglected, such lenses can harm the eyes.
• Extended wearing - were designed to be used not only during the day, but also at night. Therefore, such products can be used without removing them for 7 days and 6 nights, and after 7 days they are thrown away. Their composition contains more moisture than the previous type.
• Continuous wearing — it is allowed to use such SCLs for 30 days if they are made of silicone hydrogel material. In the case of hydrogel lenses, it is highly undesirable to leave them on overnight, as they do not allow oxygen to reach the cornea well.

How long you can wear lenses depends on their type, but wearing SCLs during the day is in any case safer than their continuous use. It is many times less likely to lead to various diseases organ of vision, including inflammatory processes and irreversible changes in the cornea.

Why do your eyes need a break from lenses?

It is advisable to use any contact lenses, regardless of their cost and quality, during the day and be sure to remove them at night, as the eyes need rest. This type of wear is safe because the cornea is constantly wetted by blinking. During sleep, the eyelids are closed, so the eyes in the lenses experience dryness and also cannot effectively clean themselves.

What happens if you don't remove your lenses at night?

There are many consequences:

• Edema. Due to the fact that the cornea receives oxygen directly from the atmosphere, SCLs interfere with its normal gas exchange. As a result, it begins to starve, and various complications form in the form of edema or the proliferation of newly formed vessels on its surface.
• Infections. Due to improper wearing of SCLs, the normal outflow of carbon dioxide is disrupted, which leads to susceptibility to the addition of microbes.
• Allergy. Antibodies appear on the surface of the lens, under the influence of which allergic reactions can occur.
• Development of dry eye syndrome. With this syndrome, wearing lenses becomes impossible due to the appearance of severe burning and stinging in the eyes.
• Irritation and inflammatory processes. The tear film contains fats, proteins, and calcium that come into contact with the contact lens. Deposits appear that begin to accumulate if a person wears SCL continuously. Because of this, irritation develops, and the patient scratches and rubs his eyes. Eventually wrong mode wearing the product may develop inflammatory process – .
• Corneal injury. Deposits cause the surface of the contact lens to become rough and uneven, which can cause injury and inflammation to the cornea. Microbial keratitis or corneal ulcers form, which are serious and dangerous complications, leading in some cases to blindness.

What if it is not possible to remove the lens at night?

There are unforeseen situations from which a person has nowhere to put the lens. In such cases, daily lenses are ideal. With them, the user of SCLs does not have to worry about where to place the product if there is no container. Their advantage is that at the end of the day, the removed lens is thrown away, and the next day you need to put on new products.

If the SCLs are worn for extended periods, but there is no solution for storage, you can put them in a regular glass with clean water to prevent drying out. In the morning, place in a container with lens solution for 4 hours, and before putting on, wash thoroughly in the solution.

If, after all, a person falls asleep with an SCL, in the morning he will feel unpleasant consequences: Dry eyes, a feeling of sand or dust, itching and burning will appear. Therefore, after waking up, it is recommended to drip a multifunctional solution into your eyes.

In what cases is it permissible to sleep in lenses?

It is believed that nap in SCL with a duration of several hours will not affect the condition of the eyes in any way. However, you should not fall asleep wearing any contact lenses that are not designed for overnight wear.

In case of extreme need, extended and continuous wear lenses can be used to sleep, but it is advisable to give the organ of vision a rest at night. It is recommended to instill drops or a multifunctional solution before going to bed and the next day, and then use glasses for several days to allow the eyes to recover.

How to remove lenses correctly

Beginners often experience certain difficulties in removing MCL from their eyes. In fact, they are quite easy to remove.

Step-by-step instruction:

1. Raise your eyes up and pull down the lower eyelid with the middle finger of your active hand.
2. Place the pad of your index finger on the bottom edge of the lens.
3. Slide the lens down or to the side, carefully pinching it between the large and index fingers, and remove it from the eye.
4. Clean the lens and place it in a container with a solution for disinfection and storage.

Many people sometimes neglect the rules for using contact correction products and wear lenses without removing them. Unfortunately, such actions do not go unnoticed. In most cases, a person experiences a feeling of sand and pain in the eyes, but sometimes misuse leads to the development of inflammation and deterioration of vision.

Ophthalmologists strongly recommend wearing them exclusively during the day, removing them at night. If this is not possible, try to remove your contact lenses at least once every 2 days. When the first signs appear eye diseases, you should immediately seek help from a specialist.

Contact lenses today are made primarily from soft materials. They consist of 30-80% liquid, and therefore are very comfortable and do not cause dryness, fatigue, etc. unpleasant symptoms. Let's find out whether there is a period of adaptation to contact optics and how many hours beginners can wear them in the first days.

Today, many people with refractive errors choose contact lenses. The advantages of this correction method are undeniable. They are much more convenient and correct vision better. In addition, modern models contact optics made from hydrogel-based materials. Lenses made from it are as comfortable as possible, they have virtually no contraindications, and are suitable for people with dry eye syndrome, hypersensitivity corneas and a tendency to allergies. Do novice users need to get used to such contact optics? Let's learn how to wear lenses in the first days.

How many hours can you wear lenses in the first days?

Contact optics are selected together with an ophthalmologist during the examination. It includes several stages. First, your doctor will determine whether a correction method such as contact lenses is suitable for you. There are a number of contraindications to them, absolute and temporary. If none are found, the next stage will begin. The ophthalmologist will check the patient's visual acuity, measure the parameters of the cornea and calculate the characteristics of the ophthalmic products that you will wear. The examination will also examine the condition of the tear film and the sensitivity of the cornea. The data obtained will become the basis for the choice of material, replacement schedule and wearing mode of contact optics. During the selection process, it will become clear how many hours a day you can wear the lenses. Moreover, the doctor will tell you how to get used to them at the very beginning.

Even if the selected contact optics is the most comfortable, it is still perceived by the eyes as foreign body. Therefore, after selecting and purchasing the first model, it is recommended to visit the ophthalmologist again after two weeks to undergo a follow-up examination. Typically, the ophthalmologist advises wearing lenses for 4 hours in the first few days. This time can be increased by one hour every day. In a week you will already be wearing them for 10-12 hours or for the time during which a specific model can be used per day. Some modern ophthalmic products can be left on the eyes for 14-16 hours. However, at the first unpleasant symptoms or feeling of discomfort, you should remove your contact lenses and visit a doctor. You may have to choose a different model.

Now let's look at another question: how long can you wear lenses and why shouldn't you wear them over?

How long can you wear contact lenses without removing them?

The duration of daily use of contact optics is determined by its characteristics and the instructions of the ophthalmologist. Thus, colored models are not recommended to be worn for longer than 6-8 hours. However, some decorative lenses, for example, scleral ones, cannot be left on the eyes for longer than 2-3 hours.

The higher the gas permeability of products, the longer hours they can be worn. There are models that can be used in a flexible or prolonged mode. You are allowed to sleep in them. This method of using contact optics must be approved by a physician. For people with corneal hypersensitivity, leaving lenses on their eyes overnight is contraindicated. It is also better to avoid this regimen when wearing lenses in the first days, that is, during the period of adaptation.

Why can't you rewear your lenses?

Why is postterm pregnancy dangerous? Each model has its own wearing mode. It must be adhered to. If you wear lenses too long, the risk of developing hypoxia increases - oxygen starvation. The cornea receives nutrients from external environment.

Ophthalmic products limit oxygen access to the cornea. If they are constantly overextended, swelling of the cornea and the ingrowth of newly formed vessels into it may occur, which is accompanied by a decrease in vision. In addition, improper handling of lenses leads to deterioration of their properties, especially for planned replacement models. While wearing contact optics, lipid and protein deposits remain on its surface, which are contained in the tear fluid. They reduce optical performance, negatively affect the permeability of the material to oxygen and can become a source of spread of microbes. In other words, wearing such lenses will be unsafe.

Is it dangerous to overstay one day? Disposable models are considered the most comfortable and safe for the eyes. They don't need to be looked after. There is virtually no risk of introducing bacteria and fungi into the eye. After removal, ophthalmic products are discarded. When purchasing a specific model, pay attention to how much the lens can be worn per day. They are usually designed for 8-10 hours. Overwearing them is just as dangerous as any other contact optics. Due to constant hypoxia, severe pathological processes In eyes. As a result, your doctor may permanently prohibit you from wearing contact correction products.

Which lenses to choose?

If you are purchasing contact lenses for the first time, it is better for you to opt for daily lenses. They cost a little more than planned replacement models, but they are more convenient to handle. In addition, daily lenses have high oxygen permeability and moisture content. These parameters are especially important during adaptation. The higher they are, the faster you will get used to ophthalmic products. The following models are popular:

• 1-Day ACUVUE TruEye - developed by Johnson & Johnson. The lenses are designed to correct myopia and farsightedness.
• Dailies AquaComfort Plus (Alcon) - aspherical ophthalmic products with a high moisture content of 69%. This model will work even if the cornea is prone to dryness.

• — contact optics made of biocompatible material Bioxyfilcon A. It is suitable for hypersensitive eyes.
• Clariti 1 day toric from CooperVision. These lenses are used to correct astigmatism. They have a toric design to correct this refractive error, as well as the myopia and hypermetropia that often accompany it.
• Dailies Total1 Multifocal from Alcon. This is one of the most modern models. It is made from water-gradient material. In the center it is moistened by 30%, and on the surface this figure increases to almost 100%. These lenses are prescribed to people with presbyopia.

After you get used to the means of contact correction, you can choose a model with a different replacement schedule. On our website you will find a large selection of lenses of all types.

Most contact optics models are designed for daytime use. They can be left on the eyes for several hours a day. Sleeping in such ophthalmic products is contraindicated. This can lead to various diseases and vision impairment. Let's find out what happens if you don't remove your lenses for a week.

How long can you keep your lenses in?

There are 4 modes of wearing contact optics:

• Daytime: can be left on the eyes for several hours a day - from 3 to 16 hours, depending on the specific model. You should not sleep with this type of contact lenses.
• Flexible: can be worn for 2-3 days without removing.
• Extended: suitable for wearing for 7 days.
• Continuous: you don’t have to shoot for a month.

The operating mode of ophthalmic products depends on two main factors:

• model parameters: gas permeability, moisture content, thickness.
• medical indications.

Thus, people with dry eye syndrome or increased sensitivity of the cornea can only use lenses during the daytime. Moreover, in such cases, one-day models with increased hydrophilic properties, that is, the ability to retain moisture on their surface, are usually prescribed: Proclear 1 Day, Dailies AquaComfort Plus, Biotrue ONE day.

So, is it possible to sleep with contact lenses? Hypothetically, yes. Today, contact optics are made from soft hydrogel materials that provide maximum wearing comfort and safety. In the absence of contraindications, you can choose a model with a flexible, prolonged or continuous method of use. For example, we list the popular models of this type:

• Air Optix Night & Day Aqua (Alcon) are silicone hydrogel lenses that transmit up to 175 units of oxygen. These ophthalmic products can be left in place for 30 days.

• ACUVUE Oasys with Hydraclear Plus (Johnson & Johnson) is a two-week contact optic. If you wear it prolonged, that is, 7 days in a row, the service life of the model is halved.
• PureVision 2 HD for Astigmatism (Bausch + Lomb) are toric lenses you can sleep in.
• Biofinity multifocal (CooperVision) - products with a multifocal design and different ways operation. Biofinity is suitable for correcting presbyopia. The gas permeability of the material is 142 Dk/t, and the moisture content is 48%.

Before purchasing lenses, you must undergo an examination, during which the doctor will determine whether you can wear contact lenses and in what mode. Why is it important to stick to it? Let's look at the consequences of wearing contact correction equipment incorrectly.

What happens if you don't remove your lenses for a week?

If they are overdue, the risk of developing:

• Hypoxia - oxygen starvation. This manifests itself in swelling and fatigue in the eyes. Subsequently, hypoxia can lead to the growth of blood vessels into the cornea and its clouding.
• Allergies. With constant contact of the conjunctiva with the material of the ophthalmic product, it may occur allergic reaction, which is accompanied by itching, burning, lacrimation and other symptoms.
• Infections. Absence daily care behind lenses often becomes the cause of microbial keratitis and other infectious and inflammatory ophthalmic pathologies.
• Dry eye syndrome. Dryness of the cornea or connective membrane is a common sign of non-compliance with wearing contact lenses.

These diseases require long-term treatment, during which time you will have to abandon the means of contact correction. In addition, protein and lipid deposits get on the surface of ophthalmic products. If they are not removed, the optical properties of contact optics deteriorate. It will not provide a high-quality image, which can lead to vision impairment. All these complications arise not only due to their overmaturity. It is also very dangerous to wear expired contact lenses. Often different eye diseases arise due to untimely replacement of optics.

How long can you leave your contact lenses on in the first days?

Now we’ll find out how many hours contact lenses can be worn by novice users. Today, mainly soft contact lenses are used, which are made on the basis of hydrogel. They are quite thin, very elastic, and therefore you don’t need to get used to them for a long time. Nevertheless, ophthalmologists recommend wearing the products for 3-4 hours in the first days, gradually exceeding this time by 1 hour. Within a week you will be able to use the lenses in the mode for which they are intended. Thus, scleral models should not be left on the eyes for more than 2-3 hours. The most modern products made from water-gradient material (Dailies Total 1) can be left on for 14-16 hours.

Is it possible to sleep in lenses with decorative properties?

Color contact optics are also made from hydrogel and silicone hydrogel polymers. There are even models that are very highly breathable, such as the Illusion Geo from Belmore Contact. But they cannot be used in a flexible or prolonged mode. The coloring pigment reduces the Dk/l value. The access of oxygen to the cornea is limited. There is a risk of hypoxia. Colored models can only be worn during daytime.

So, now you know how long you can wear your lenses without removing them, whether you can sleep in them, and how long you should wear them in the first days after fitting them.

We list a few basic rules that must be followed when using contact optics to avoid complications:

• use only correctly selected lenses;
• do not wear expired models;
• follow the wearing regime;
• Carefully care for your optics using special solutions.

If you wear lenses in extended mode, put moisturizing drops into your eyes if necessary. If unpleasant symptoms occur—redness of the conjunctiva, burning, dryness—consult an ophthalmologist.

Contact lenses that can be worn for 30 days without removal are an innovative product that opens up a whole new level of freedom for users with vision problems. If regular lenses are mandatory need to be removed at night, then in the case of monthly lenses everything is much simpler and more convenient. During the entire period you can forget that you are using contact correction.

What you need to know about extended wear lenses?

Among all types of contact lenses, they deserve special attention. Their key feature is that such lenses, unlike classical vision correction devices, are allowed for continuous wear (even during sleep) for up to 30 days.

The use of contact lenses requires careful care and obligatory adherence to hygiene rules. Regular contact lenses have to be removed every evening. If you leave them in front of your eyes while you sleep, you can get a serious illness.

Modern manufacturers of optical products have taken care of the convenience of contact lens wearers. Today's extended wear lenses are made from newest material– silicone hydrogel, characterized by high oxygen permeability. The rate of air access to the cornea of ​​the eye is very important for the safety of contact lens wearers.

The higher it is, the greater the protection against the accumulation of protein deposits on the cornea of ​​the eye. Maximum biocompatibility – key characteristic of monthly wear lenses. The user will not have to do it every day. But, despite the possibility of not removing them for a whole month, most experts agree that it is better to remove them from time to time (at least once a week) at night and clean them using peroxide systems.

Monthly lenses are very thin and comfortable. They contain substances that constantly moisturize the cornea, allowing it to breathe freely.

That is why you can leave them on for a whole month. Such lenses are designed specifically for those people whose lives do not fit into the traditional regime. They are ideal for people with irregular work schedules, 24/7 jobs, such as truck drivers or security guards. Contact cards are indispensable for nightlife lovers, and they are also perfect for students.

“30 days without removing” lenses have become very popular. You can wear them for a whole month without taking them off day or night. If desired, you can use only daytime wearing mode or a combined one: sometimes take it off at night, and sometimes not.

Flexible wearing schedule – exactly what doctors recommend to reduce all risks of corneal inflammation to zero. If the wearing mode is daily or flexible, then the lens must be stored in solution. If the wearing regime is long-term (all 30 days without removing), then the solution is not needed.

Leading brands of contact lenses intended for monthly wear:

• Air Optix Aqua Night&Day(“Ciba Vision”);
• PureVision, PureVision 2 HD(“Bausch & Lomb”);
• Maxima(“Maxima Optics”);
• Biofinity, Biomedics 55, Proclear(“Cooper Vision”);
• Mediterranee, Compatic, Air(“Carl Zeiss”).

How to wear it correctly?

Monthly contact lenses can be daily or extended-wear. The first ones must be removed at night and stored in special containers with solution for contact lenses. Extended wear lenses can be worn for a month without removal. They don't need a solution.

Each lens is contained in an individual blister. The wearing period of 30 days is counted from the date of opening the blister.

For convenience, the lenses are lightly tinted and have a side indicator, which makes them easier to find in the solution. There are monthly lenses with a beginner-friendly shape that makes them easier to handle. This allows them to be removed and put on without damage, even for unadapted users. An ophthalmologist or contact specialist will give you competent recommendations on putting on, wearing, and storing lenses correctly.

Read about the degree of myopia in.

New lenses with high Dk (a measure of oxygen permeability) open up the possibility of long-term wear for people. However, prolonged wearing Not recommended people:

• with immune system disorders;
• with severe allergies;
• systematically taking medications;
• problematic patients who have previously experienced intolerance to contact lenses (for example, papillary conjunctivitis).

Also, long-term wearing is unacceptable for people who have had problems with daytime wearing and for those who have tried to wear them without success. 6 days in a row. If a person wants to immediately start using extended-wear lenses, then an adaptation period of at least one week should be provided for him with a daily regime of wearing lenses. Then you can only switch to prolonged wearing for 6 days, after which an examination by a doctor should follow. If no problems arise, the patient can switch to 30-day wear. This schedule will allow the eyes to get used to the lenses and determine the reaction of the cornea to the silicone hydrogel material.

Contact lenses for 30 days

For monthly lens wearers should be remembered:

• Even if the lenses are designed for continuous use for a month, a flexible wearing mode is still preferable.
• Lenses should be removed if discomfort occurs.
• Filmed on a short time The lens should be disinfected before putting it on.
• Do not use expired lens care products that have expired.
• 30 days is the maximum period of continuous wearing of such lenses. Don't experiment and try to wear them longer. After this period, lenses lose their properties and can cause various inflammations of the cornea of ​​the eyes.

conclusions

The creation of silicone hydrogel contact lenses has become a huge step forward in the fight against hypoxia. This invention gave patients the opportunity to wear lenses for a long time, comfortably for up to 30 days. However, it is important to properly prepare your eyes for prolonged wear, and their wearing regimen, follow the rules of hygiene and lens care, and also conduct regular eye examinations with a contact specialist. If you need daily contact lenses, you can buy them, but consult your doctor before purchasing.
