Causes of different vision in the eyes
Greetings, Dear friends, readers of my blog! I often hear people complain that one eye sees worse than the other. Why does it happen different vision on the eyes (anisometropia)? What is this connected with? And, most importantly, what should you do to prevent this from happening to you? I will try to answer these and other questions in my article.
Important Organs
Eyes are one of the important human organs. After all, thanks to our eyes, we receive the most information from the world around us. Despite this, we often do not worry when our vision deteriorates. Some people think that weakening vision is due to age or overwork.
Indeed, visual impairment is not always associated with illness. This may be due to fatigue, lack of sleep, constant work at the computer and other reasons. And, it’s true, sometimes in order to normalize vision, you just need to rest and do eye exercises. Exercising can help improve vision and train the eye muscles. But if the exercises still do not help, and your vision continues to deteriorate, then you need to consult a doctor.
What are the causes of different vision in the eyes?
When people's vision declines, they try to correct it with the help of
glasses or lenses. But it happens that vision deteriorates in only one eye. Such symptoms can appear in both children and older people. When a person experiences unilateral visual impairment, his life becomes uncomfortable. It's okay if the difference in vision is not very great. What if it’s big??? Different visual acuity can lead to stress eye muscles, headaches and other problems.
The causes of different vision in the eyes can be either congenital or acquired. Most often, people exhibit congenital (hereditary) anisometropia. So, for example, if a person already has anisometropia in the family, then, most likely, this disease can develop in the next generation. But you need to take into account that in childhood it may not appear at first, but in the future it sometimes leads to bad consequences.
And it doesn’t matter at all which eye of the parents sees worse: this disease in a child can manifest itself in any eye.
One of the reasons for vision deterioration in children is heavy workload at school, prolonged viewing of television programs, and excessive hobbies. computer games. As a result, only one eye begins to see worse due to excessive strain. Most often this is preceded by headaches, severe fatigue, nervous tension. In adults, the cause may be a previous illness or surgery.
How do we feel about it?
Retinal images become different sizes due to asymmetrical projection. In such a situation, usually one eye captures the picture better than the other. Images become blurry and may merge. The perception of what is seen is distorted and may become double. The world perceived as blurry and indistinct. This can lead to the fact that a person finds it difficult to navigate in space and has a slow reaction to any external stimuli.
Lazy eye
In order to somehow compensate for this deformation, our brain reflexively “turns off” the eye that sees poorly. After some time, he may stop seeing completely. In medicine it even exists special term– “lazy eye” (amblyopia).
What to do?
Anisometropia is usually treated in two ways. The first is wearing telescopic glasses or corrective lenses. But I would like to emphasize that in no case should you choose glasses or lenses on your own without the advice of a doctor. This, on the contrary, can only worsen the situation. In addition, this can lead to microtraumas of the cornea, and, as a result, to infection in the eye, inflammatory processes and swelling.
Ophthalmologists confirm that with a disease such as anisometropia, it can be difficult to choose a correction.
The second method is surgical. It is resorted to only as a last resort, when all other methods do not work. Most often this happens at the stage chronic disease. The operation is performed using a laser.
And only as prescribed by the attending physician. This operation has some limitations and contraindications. So, for example, after surgical intervention You can’t put too much strain on your eyes, you need to try to avoid concussions and any injuries, because all this can trigger the disease again.
I would like to note that amblyopia in children can be corrected quite well. But first you need to get rid of the cause of the loss of vision in the eye, and then make this eye work again. Often, for this, doctors advise using occlusion - that is, try to exclude the second, healthy, well-seeing eye from the visual process.
Treatment must be selected strictly individually. It all depends on the age of the person, the type of pathology and the stage of development of the disease.
The best treatment is eye exercises!
One of the means of preventing anisometropia can be exercises for the eyes, reducing (or completely eliminating) watching television, working on the computer, alternating mental and physical activity, walks on fresh air. Remember that any disease is easier to prevent than to treat!
I wish you, dear readers my blog good health, a keen eye and rich, bright colors! Let everything you see around you bring you only joy and positive emotions, which will subsequently lead to success! See you on my blog!
Let's look at some symptoms of diseases based on the sense of color.
Symptoms of diseases based on the sense of color
Color perception disorder
People who use LSD or other hallucinogens, as well as people with hangovers, often see things in strange colors. But if you have nothing to do with drugs, then the distortion of the color perception of objects is known in medical language like chromatopsia - maybe early sign diabetic eye disease.
Even small changes in blood sugar levels can sometimes cause visual disturbances. In the case of a confirmed diagnosis of diabetes, color distortion complicates the process of self-monitoring blood sugar levels using colored strips that are dipped into urine. So there's one more reason to say no to cake.
Very often, diabetic athletes experience clear changes in color perception after intense training or games. This could very well be an early sign of diabetic eye disease.
If most of the things you look at have a yellow tint, you may be experiencing symptoms of a type of chromatopsia called xanthopsia. Xanthopsia warns you of developing jaundice caused by serious illness liver.
If you are taking digitalis (a medicine commonly prescribed to treat certain heart conditions) and suddenly start seeing objects in your yellow color, and even with a certain halo around, perhaps these symptoms are a warning about digitalis poisoning. Immediate medical intervention, since this condition is fraught with heart failure, cardiac arrhythmia and is deadly.
Color perception in men
If your male partner, who has always looked at life through rose-colored glasses, suddenly begins to complain that everything now appears in some kind of bluish, sad color, perhaps it is not that he is in a state of depression. Who knows, maybe he takes too many stimulants that guarantee pleasure. When a man sees objects in a light bluish haze, which is often accompanied by increased color sensitivity, we are talking about one of the common side effects use of Viagra, Cialis or Levitra, used to treat sexual disorders.
If you are being treated for functional sexual disorder and suddenly lose sight in one or both eyes, stop taking the medication immediately and contact your doctor as soon as possible. This may be a sign of non-arterial ischemic optic neuropathy, a condition that can lead to blindness. Men with retinal disease or other vision problems should avoid these drugs.
Now you know the main symptoms of diseases by the sense of color.
Treatment of diseases based on the sense of color
Some of the signs described above require immediate medical attention, others do not. But if you have doubts, it is better to visit an ophthalmologist as soon as possible. In the case of pain, changes in visual perception(especially if accompanied by nausea and vomiting) or persistent flashes of light, consult a doctor immediately. Well, no matter what condition your eyes are in, do not forget to regularly check your vision - a preventive medical examination often helps maintain proper eye function and eliminate different types medical problems. This is especially important for diabetics. The following is a list of specialists who can diagnose and treat eye diseases:
Ophthalmologist: a doctor who specializes in diagnosing and treating symptoms of eye diseases and functional disorders.
Optometrist: although he is not a doctor with higher education, but specializes in vision problems and prescribes appropriate products - glasses, contact lenses, special exercise equipment and treatment. Optometrists can recognize glaucoma, cataracts, degeneration macular spot and prescribe medications for a range of diseases.
Optician: Also not a physician, but selects appropriate glasses and offers other optical assistance as prescribed by an ophthalmologist and optometrist.
When the question arises about what different vision in the eyes is called, the answer will be the same: anisometropia. Given pathological condition occurs in cases where optical system loses the ability to refract rays. That is visual organs with this disease they have different optical powers. may be accompanied by the development of astigmatism. Of course, the disease is provoked by certain factors, and without proper treatment it causes complications.
When a person is impaired visual functions, are selected effective ways corrections. This refers to the use of glasses and lenses.
But if different vision is detected in the eyes, corrective optics are not always able to help. It's all about the reasons that cause anisometropia - a disease that is characterized by the presence of different vision in the eyes.
In order for a correct and unblurred image to be formed, it is necessary that the parallel rays emanating from the object intersect at the retinal focus. If this process is disrupted, a decrease in visual acuity is observed.
When the difference in refractive power between the eyes is one or two diopters, binocular vision will not be particularly affected. But if the indicators differ significantly more, then the development of refractive anisometropia should be expected. Moreover, the refraction in one eye may be normal, but in the other it will be abnormal. But, basically, the pathology affects both eyes.
It is advisable to eliminate anisometropia in time, otherwise the patient may face dangerous consequences:
- squint;
- amblyopia (when, due to inactivity of the eye, its visual functions are lost).
Causes and types of illness
It is impossible to ignore the condition when the visual apparatus is exposed to various lesions.
You should know that different vision in the eyes can have different reasons:
- congenital;
- acquired.
Doctors usually diagnose a congenital pathology.
Acquired anisometropia occurs when:
- Progression of cataracts is observed.
- Negative consequences arise after the surgical intervention on the organs of vision.
If we talk about hereditary predisposition, then in babies under one year of age the disease is asymptomatic. With age, symptoms become more pronounced. Manifestations will depend on the extent of the disease.
It happens:
- weak (the difference between the eyes is a maximum of 3 diopters);
- medium (the difference can reach six diopters);
- strong (over 6 diopters).
In addition, anisometropia occurs:
- refractive (characterized by the presence of the same length of the axis of the eyes and a difference in refraction);
- axial (accordingly, there is a difference in the length of the axis, but the refraction is not impaired);
- mixed (both the first and second parameters have differences).
If the degree is weak, the disorders are almost not felt. When pathology of the highest degree develops, binocular vision is impaired. There is no clear image. At the same time, it is difficult for the patient to navigate in space. Often visual stress provokes excessive fatigue eye.
Whichever eye has the most severe damage, suffers more accordingly. In other words, its activity will be suppressed by the brain. The result is the development of amblyopia.
Another consequence is strabismus, which is caused by weakening of the rectus muscle of the affected eye and its deviation to the side.
Diagnostic methods and therapy
Making a diagnosis requires:
- Visometry (tables are used to determine the level of acuity).
- Perimetry (thanks to a certain device, the boundaries of the visual fields are revealed).
- Refractometry.
- Skiascopy (refractive power is determined using a light beam and a mirror).
- Ophthalmoscopy (the doctor uses an ophthalmoscope to examine the bottom of the eye).
- Ophthalmometry (the radius of curvature of the cornea is determined using an ophthalmometer).
- Study of binocular vision (synoptophore and four-point color test are used).
The method by which the pathology will be eliminated is determined by the level and type of refractive errors. Visual dysfunction is usually corrected with glasses or contact lenses. But this method is not suitable for every patient. It is necessary that the difference in refractive power should not be more than 3 diopters. 
The selection of lenses is carried out for each specific case separately. It is necessary to wear them correctly and periodically undergo examination by an ophthalmologist, receiving the necessary advice from him.
A patient who wears lenses may suffer from:
- epithelial edema;
- keratitis;
- damage to the corneal layer.
If conservative methods turned out to be useless, the doctor decides to carry out laser surgery. It is also prescribed to patients whose degree of illness is high. After surgery, it may take a week or two for the improvement to become apparent.
There is no need to panic when anisometropia is diagnosed. If detected early, the problem can be completely eliminated, especially if there is weak degree diseases.
