Why does one eye see warmer colors and the other colder? and got the best answer
Answer from Baturin[guru]
According to the evolutionary theory of asymmetry (), the evolution of any structures (and information flows) goes from symmetry to asymmetry. Asymmetrization along the top-bottom axis occurred under the influence of the gravitational field. Asymmetrization along the front-back axis occurred during interaction with the spatial field, when fast movement was needed (to escape from a predator, to catch up with prey). As a result, the main receptors and the brain were located in the front of the body. Asymmetrization along the left-right axis occurs in time, that is, one side (organ) is more advanced, “avant-garde” (as if in the future), and the other is “rear-guard” (still in the past).
Dominance is a form of asymmetry. The dominant hemisphere or organ performs its functions better and is therefore more preferable. A person can be strongly right-handed in one function (writing), weakly left-handed in another (grabbing), and ambidextrous (symmetrical) in a third.
It is assumed () that during the Mesozoic period, early mammals occupied a subordinate position in relation to the “reigning reptiles” (especially dinosaurs), had small sizes and a twilight lifestyle. sunlight has the greatest intensity in the green and red (warm) parts of the spectrum, and in twilight lighting the cold (blue) part of the spectrum is of greater importance.
Geodakyan attributes the lower end, the back part, right hemisphere brain and left side bodies to conservative subsystems. At the same time, the flows new information coming from the environment to the operational subsystems (upper end, front part of the body, left hemisphere brain and Right side body) are directed from top to bottom, front to back and left to right for the brain (right to left for the body). A new character arises at the operative end and, if it is not needed there, drifts in phylogeny towards the conservative end.
From me: Based on what has been said, it can be assumed that for most people, warm colors are seen better by the right eye, and cold colors by the left.
Again from Geodakan:
The left eye is more sensitive to simple signals (flash of light), and the right eye is more sensitive to complex signals (words, numbers) (old and new stimuli). The left eye is more sensitive to ordinary words, and the right eye is more sensitive to brands (old and new words). Environmental sounds (the sound of rain, sea, dog barking, coughing, etc.) are heard better left ear, and semantic (words, numbers) - right (old and new sounds). In humans, according to dichotic speech signals, in the first days there is an advantage of the right ear, and after a week - the left. Recognizes familiar objects better by touch left hand, and unfamiliar - right (old and new objects)

good question! I would like to know myself!
Answer from Mikhail Levin[guru]
I compared it - mine is exactly the same.
But my square frame seems taller to one eye than it is wider, and wider to the other eye than it is taller. Normal astigmatism

are you really human?
Answer from Releboy[guru]
The terminator's eyepiece settings are wrong?? ? And it’s not just the eyes that see differently. Dashenka, try on your arms and legs - surely which one is longer, the other shorter? And you go to an otolorhinologist and find out that one ear hears one frequency range, the other hears another. A right lung more than the left by two lobes. Why read? After all, these are people, not clones. If everyone were the same, there would be no need for doctors. It would be enough to issue universal instructions for treating humans...

My situation is even better - one eye sees everything with a greenish tint, the other with a reddish tint. Together is fine.
Some kind of 3D.
Answer from Edward Unknown[guru]
Working as an amateur on a tacheometer during the day, I sometimes rolled my left eye so much that it actually saw an almost black and white image.
Why as an amateur? because the pros in schools teach you to look in turns ^_^ left/right
Answer from Mikhail Zhukovsky[newbie]
I have the same thing myself. I noticed that it depends on the lighting. If, for example, the lamp was on the right, then the right eye sees colder than the left.
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 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.
One eye sees warmer tones, the other cooler. For about a year now, the left eye sees worse than the right, and everything is dark colors, as if through the prism of “cloudy”, and the right one, on the contrary, in warm colors. Is this normal? The vision itself is poor. With my left eye I can hardly distinguish letters in the distance, only close up, and even then with difficulty. During the examination they said that everything was fine with the eyes. Should I be worried and what could it be?
Good afternoon, Alexander! Unfortunately, we cannot assess the condition of your visual system and make a diagnosis in absentia. Please note that if vision is not 100%, then it cannot be said that “everything is fine” with vision. The complaints you mentioned may be a sign various diseases– accordingly, treatment tactics will be different. IN in this case We recommend that you contact comprehensive examination visual system in a specialized ophthalmology clinic.
When ophthalmological pathologies occur, changes in both organs of vision are more often observed. But there are cases when the problem is limited to one eye. This may be expressed in different forms, but a common option is a significant decrease in visual acuity in one eye (one eye sees brighter than the other).
This pathology occurs due to various reasons. The condition when one eye sees worse than the other is called amblyopia in medicine.
Terminology includes dysfunction of the visual center. Physical damage to tissues and mucous membranes has nothing to do with this.
Amblyopia is recognized by the following signs:
- difficulty determining the shape of distant objects;
- incorrect assessment of the distance to distant objects, etc.
As the pathology develops, a loss of binocular vision occurs. Patients find it difficult to focus on an object while looking at it with both eyes.
Reference! The problem of vision loss in one eye occurs regardless of age. According to statistics, amblyopia is more often diagnosed from 6 years of age.
The main provocateurs of pathology are diseases of the organs of vision. But the impact on the visual center of one eye and diseases that have nothing to do with ophthalmology cannot be ruled out.
Eye diseases
If vision decreases in one eye, and after a few minutes/hours the symptom goes away, there is no need to worry. This phenomenon often becomes a consequence nervous overstrain, severe eye fatigue after hard work. It is worth seeing a doctor if lazy eye syndrome persists for 2-3 days.
The cause of loss of binocular vision can be ophthalmological diseases:
- age-related changes in the retina and lens of a destructive nature;
- congenital anomalies;
- strabismus;
- , myopia;
- weakness of the accommodative apparatus of the visual system;
- transferred viral infections eye.
Third party diseases
In addition to pathologies of the visual organs, provoking factors are:
- past infectious and viral diseases;
- pinched cervical nerve;
- oncology;
- premature birth (prematurity of the fetus), etc.
Why does one eye see brighter in the morning?
In the morning, every person feels slight discomfort in the eyes, which goes away within 1-2 minutes. This normal phenomenon. If one eye perceives objects and objects more brightly than the other, but the effect does not go away long time, it is recommended to contact a doctor for a thorough examination eyeball.
After alcohol
One of the reasons for morning distortions of the visual apparatus may be negative impact alcohol if you have drunk a fair amount of strong drinks the day before. Ethanol contributes to dehydration of the body, decreased functioning lacrimal glands, which provokes dry eye syndrome.
Large doses of alcohol impair vision due to the effects of toxins. Against this background, toxic amblyopia develops. Signs of pathology are especially pronounced during a hangover, that is, in the morning hours.
Why can this happen suddenly?
Symptoms of amblyopia that appear in the morning are often evidence of incorrect head position during sleep. When the face is immersed in a pillow, the visual system is compressed under the weight of its own body.
This leads to disturbances in blood flow to the tissues and cells of the eye, tear production, and slight deformation of the cornea. After waking up, the pinched eye cannot focus on objects. Discomfort is often complemented by bright flashes.
After 5-10 minutes, visual acuity is completely restored. If symptoms do not disappear for a long time, you should make an appointment with an ophthalmologist.
The mechanism of development of the problem
The development of amblyopia often begins in childhood. The mechanism of the pathology can be traced to the poor image transmission of one eye.
Receiving signals from both organs of vision, the brain is not able to create a complete chain. As a result, a person sees objects in a blurry or bifurcated form.
Systemic reception of distorted signals forces the brain to refuse interaction with the diseased eye, as a result of which the visual organs develop asynchronously. This triggers the development of other ophthalmological pathologies.
Types of Amblyopia
By analyzing the patient's examination data and the etiology of amblyopia, specialists determine what type it is.
- Refractive – the provoking factor is the constant formation of a distorted image on the retina due to lack of treatment and refusal to wear corrective optics.
- Dysbinocular – the main cause of the pathology is strabismus.
- Obscuration - passed on from generation to generation ( hereditary factor). Vision problems also occur when congenital diseases(cataract, ptosis).
- Anisometropic - the problem arises against the background of reduced vision in one eye, which lags several diopters behind the dominant one.
Who's at risk
The pathology can develop in any person, but those people whose relatives had ophthalmological problems are especially susceptible to amblyopia. Patients diagnosed with the following diseases are automatically included in the risk group:
- strabismus;
- myopia;
- farsightedness;
- astigmatism;
- cataract;
- cerebral palsy.
Sick children, premature babies, and newborns whose weight at birth was less than 2.5 kg are susceptible to pathology.
There is a predisposition to deterioration of vision in one eye in children who have congenital forms of cataracts and signs of anisometropia.
Diagnostics
To study the pathology, a thorough examination of the eyeball and the patient’s health in general is carried out. Diagnostics includes a set of measures, which includes:
- examination by an ophthalmologist;
- examination of the structure of the eye using a slit lamp (biomicroscopy);
- determination of IOP (tonometry);
- Ultrasound of the organ of vision to identify pathologies;
- determination of the refractive power of a light beam (refractometry).
To complete the picture, the attending physician may prescribe blood and urine tests.
Subsequent treatment
Purpose therapeutic measures is to eliminate the causes that led to vision deterioration. A large list of provoking factors requires an expanded process of diagnosis and development of treatment strategies.
The doctor must set the patient up for a long course of therapy and comply with all prescriptions.
Conservative
Traditional treatment using conservative techniques gives high therapeutic effect with early diagnosis. In the fight against pathology the following are used:
- special medications;
- dressings applied to the healthy eye to restore lost function in the amblyopic eye.
Along with drug treatment the patient is prescribed:
- vibration massage;
- reflexology;
- special diet;
- vitamin complex;
- wearing special glasses (occluders);
- exercises on an eye training apparatus.
Surgical
When diagnosing amblyopia of refractive and anisometropic types, it is often prescribed laser correction. The operation does not involve deep penetration into the eye tissue, therefore it is considered less traumatic and does not require long-term recovery.
Along with laser it is practiced surgical intervention. Basically, operations are performed to change the position of the eyeball, remove cloudiness or replace the lens. This approach makes it possible to combat serious illnesses that were not treatable by other means.
Traditional methods
Recipes traditional medicine recommended to be combined with traditional treatment. Expect great results from using exclusively medicinal herbs and others homemade remedies not worth it. And when integrated approach the effectiveness of therapy actually increases.
Effective recipes for amblyopia:
- drinking freshly squeezed juices from nettles, black currants, blueberries;
- applying lotions from cornflower infusion;
- wiping the eyes with a swab dipped in aloe juice;
- ingestion of parsley infusion;
- lotions from a decoction made from herbs (dry eyebright and hernia);
- drinking green tea with the addition of ginseng.
In the fight against amblyopia and for preventive purposes, patients are recommended to perform special complex exercises for the organ of vision in order to train muscles and restore the sensitivity of nerve impulses.
Features of therapy in children and adults
If the pathology is diagnosed at an early stage, the chances of full recovery are increasing. Thanks to timely surgery to correct the position of the eyeball and correct refraction, it is possible to normalize the functioning of the visual apparatus.
The organ of vision is actively developing in childhood. When diagnosing amblyopia in a child, it is important to have surgery before the age of 12. In most cases, pathology is detected during the passage medical commission for admission to preschool or school. This ideal age to eliminate the problem, if you do not delay treatment.
The principle of therapy for adult patients is based on long-term direct occlusion of the healthy eye and stimulation of the foveal zone of the diseased organ of vision. Among the techniques used to eliminate amblyopic manifestations, technology based on the effect of neuroplasticity stands out. It is performed using a computer program that shows the patient different stimuli based on the Gabor spot. The effectiveness of this therapy is an improvement in visual acuity by 2.5 lines.
Possible complications
If treatment is not started promptly, the progression of lazy eye syndrome will rapidly continue until complete loss of functionality. Problems with complications also concern those patients who did not receive full treatment or refused traditional therapy or surgery. Therefore, the issue of early diagnosis and quality treatment should be a priority.
Children require special attention. In the presence of pathological processes Treatment cannot be delayed. Lost time results in irreversible changes, which subsequently negatively affect the quality of life.
Prevention
If there are risk factors that provoke the development of amblyopia, it is recommended to carry out timely preventive actions to maintain visual acuity.
- Pass annually preventive examination an ophthalmologist to identify pathologies.
- When manifested alarming symptoms you need to go to the clinic for an examination. Early diagnosis increases the chances of a full recovery.
- If the left or right eye does not perceive objects well, it is worth periodically putting a bandage on the healthy organ of vision in order to train the muscles and visual apparatus of the lagging side.
- Special eye exercises will help early stages suspend and correct pathological processes.
- Limit the time spent reading a book or computer.
- Use only high-quality cosmetics.
- To refuse from bad habits.
Healthy eyes and sharp vision help a person realize his dreams and personal developments. This gives a reason to feel like a full-fledged member of society.
