One eye sees warmer tones, the other colder. For about a year now, the left eye sees worse than the right, and everything is in dark colors, as if through the prism of "cloudiness", and the right one, on the contrary, in warm colors. Is it normal? Vision itself is bad. With my left eye, I can hardly distinguish letters in the distance, only near, and even then with difficulty. During the examination they said that everything is in order with the eyes. Should I be concerned and what could it be?

Good afternoon Alexander! Unfortunately, we cannot evaluate the state of your visual system and make a diagnosis in absentia. Please note that if the vision is not 100%, then it cannot be said that “everything is in order” with the vision. The complaints indicated by you may be a sign of various diseases - accordingly, the treatment tactics will be different. IN this case We recommend that you apply for a comprehensive examination of the visual system in a specialized ophthalmological clinic.

Different perception of the organs of vision does not always indicate the presence of a pathological condition.

The difference in color perception may not be expressed significantly, which indicates a certain norm of vision.

A significant difference in the color display of the picture is the reason for seeking medical help.

The reasons for the different perception of shades are congenital or acquired. With hereditary pathology, both eyes are affected. In the case of acquired color blindness, one-sided progression of the disease is observed. Violations of color perception develop against the background of a pathological condition in the body:

• diseases of the retina;
• violations in the functionality of the central nervous system;
• jaundice;
• misapplication medicines;
• poisoning with chemical components or their compounds;
• due to cataract removal;
• prolonged exposure to the visual apparatus of ultraviolet rays.

Acquired violation of color transmission from the eyes to the brain, there are several types:

• xanthopsia. Surrounding objects become yellow.
• Cyanopsia. The picture is perceived in blue shades.
• Erythropsia. Vision is colored red.

The appearance of acquired disorders in the susceptibility of a color picture is temporary. Elimination of the pathological condition occurs after reducing the impact of provoking factors.

Complete loss of color perception by the organs of vision is characterized by additional pathological conditions:

• lowering the level of vision;
• central scotoma.

There is partial blindness to some shades of colors. Classify such color perception according to shades:

• Protanopia. Insensitivity of the eyes to red.
• Deuteranopia. The organs of vision do not recognize green shades.
• Tritanopia. Difficult to recognize of blue color visual apparatus.

Perhaps the appearance of complex color blindness. For example, only blue or green shades are not perceived.

Common pathological conditions are protanopia and deuteranopia.

Check at home

To test at home, you only need a bandage. Manipulation is carried out in stages:

• Closing 1 eye, you need to fix your eyes on white.
• Repeat the procedure with the other organ of vision.
• The described procedure is alternately carried out, but with a higher speed of changing eyes.
• Look at white with one eye for about 5 minutes. Then change the organ of vision.

All changes must be remembered or recorded in a convenient format.

Explanation

Due to the rapid switching of the work of the visual apparatus, when the gaze stops in a non-white color, in the absence of deviations, the same picture is observed without changes in brightness or color hue. Necessary condition To obtain a reliable result, the test is carried out during the waking period.

After removing the bandage from the eye covered with it, there should be no change in color perception. There may be a temporary increase in the brightness of the closed eye.

The different susceptibility of the organs of vision to pictures is not always based on incurable diseases. It is enough to eliminate the influence of provoking factors, which will have a beneficial effect on the restoration of vision. The presence of any changes requires consultation with an ophthalmologist to determine the provoking factors.

Why do I see different shades of colors between my eyes?

Often I see colors with a slightly different hue when looking into my eyes individually. The right eye is more red (warmer), while the left eye is usually bluer (cooler). However, sometimes I don't notice any difference in hue between the eyes (even when closing the other), and in a very rare case, the warm/cold differentiation switches (left is warm, right is cold).

My questions:

1. This is fine? Does this happen to anyone else?
2. What causes this difference between the eyes?
3. What can cause the shades to be sometimes clearly visible, and at other times not at all? Is the cause potentially environmental, behavioral, physiological, chemical, etc.?
4. I wonder if this happens at the level of the eyeball (eg cone physiology) or somewhere in my brain (eg PVC in the occipital lobe)?

If I had to guess, I would say that maybe it has to do with cone fatigue/neural adaptation, where each eye experiences slightly different stimuli and ends up with different temporal adaptations.

the forestecologist

@CactusWoman seems like a valid guess, but I've never heard of this effect affecting color perception. In addition, differences in hue perception can last for hours even with changing visual stimuli.

Rishab Bayragi

This is strange, because I also sometimes have a similar experience, perceiving different shades in each eye individually, although not always. But I don't know what is the reason..

@theforestecologist- Did you find any findings on this?

This is an interesting phenomenon that I have been aware of for several years, but I have yet to come across any official description or explanation of it.

However, this phenomenon is easy to explain. This is the result light adaptation your retina in response to different levels light received by each eye.

Background

The level of ambient light present during the day varies by as much as 10 orders, and our visual systems have evolved to accommodate this. The human retina and more recent visual processing centers have a number of ways of adapting to the light levels present in the environment. They do this all the time, but it takes a little time for these adaptation mechanisms to adjust to different light levels, usually on the order of fifteen seconds or a few minutes. That's why when you get out dark room on the sunlight, you are momentarily blinded by a (relatively) bright light.

Some of these adaptation mechanisms are color dependent, such as those found in the cone cells themselves.

explanation

TL; DR-ers, just read this section

In most cases, both of your eyes experience roughly the same levels of light intensity, both overall and for each color of light. But it is not always the case.

If you have one eye for a while, such as when you lie down, then your two eyes will be adapted to two different light sources. If you then open that eye, for a short period of time that eye will perceive the world brighter than the other eye. If the light level present in the environment also has a hue, then the newly opened eye will perceive that hue more strongly than the other eye.

DIY Science Time

You can see for yourself, as I have done for last hour, with only a temporary dressing and nothing better.

1. Check your initial state first by closing one eye and then the other and quickly switching back and forth looking at something white. If you are awake and active, the images from each eye should have approximately the same hue and intensity.
2. Close one eye completely (without pressing it) for about five minutes, leaving the other eye open.
3. Then remove the bandage and close each eye again.

If my hypothesis and explanation are correct, the previously covered eye should see the world slightly brighter and brighter than the uncovered eye (the shade of that shade should depend on your light source).

If you guys are really doing this, you should report your results in the comments, especially if your results show an error with my hypothesis. Let's do science, folks.

Your lenses are different colors. You develop cataracts.

I noticed it too. I assumed that it was an early cataract in the yellow eye and this is an opportunity to do a second reading. A cataract is the lens of the eye that has yellowed and clouded to some extent with age.

Change is slow and so unless you compare one side to the other, you won't notice that everything is getting yellower. But after cataract surgery, everything is much bluer. The squares in the image below show regular white light and then as yellow it appears through the cataract. The same source.

I believe your red stained eye is a cataract. But don't worry. Cataract surgery is not a big deal.

I don't have an explanation for switching back and forth/normalization.

the forestecologist

Thanks for the interesting post. However, I think the cataract is definitely not the culprit in this case given the back and forth switching.

Which seemed to some to be white and gold, and to others blue and black, as a new dispute began in social networks. British Nicole Coulthard posted in Facebook photo of Vans sneakers and said that she and her friend see the color of shoes differently: one had gray sneakers with turquoise laces, and the other had pink with white laces.

At The Village, ten people voted for gray, and only three saw pink. For some, the color of the shoes changed by the end of the day. In fact, the sneakers turned out to be pink.

To end the debate, we talked to an ophthalmologist, a psychologist and an artist and figured out why people see colors differently and what influences this.

The reason for the different perception of colors is a violation of color vision. These violations can be established using Rabkin's tables . Color perception depends on the visual pigment, this indicator is most often congenital, but it can also be acquired - after an injury or neuritis.

Rabkin's polychromatic tables are used to detect color blindness. According to the degree of color perception, there are: trichromats (normal), protoanopes (people with impaired perception in the red spectrum) and deuteranopes (people with impaired color perception of green).

Sergey Klyuchnikov

psychologist, director of the Center for Practical Psychology

The perception of color is influenced by living conditions, the state of a person in this moment, professional training and general condition of the organs of vision. TO physiological reasons include a defect in vision, such as color blindness, as well as situational mood. In a gloomy mood, a person reacts to dark shades, and when positive mood the picture for him becomes sunny and cleaner.

Sophistication in the definition of colors also plays a role. This aspect may be related to natural conditions or special training. Northern peoples who live in Chukotka or Alaska distinguish much more colors of snow, since hunting success and survival depend on it. Professional education also plays a role: artists have a sharper palette of perception.

It is enough for an ordinary person to see approximately, and he already draws a conclusion about the picture. Due to the visual culture that has now fallen upon us, the array of color information, people stop recognizing shades, they define them rather by shape. Color has ceased to be an indicator in our conditions.

From the point of view of the emotional perception of color, it is influenced by the cultural background, social position, and upbringing of the vision of color. People associated with creative activities are distinguished by the observation of flowers. When a person constantly comes into contact with this, he sees the color more sensitively and deeper, places accents more strongly.

In order for the color to be perceived more calmly or, conversely, to cause an emotional outburst, a certain harmony of colors is created. And this combination just can affect perception. The same red can be perceived differently depending on the color around it. There are scientific papers by Joseph Albert on tools to influence the perception of colors.

Perception also differs from conditions, places. Therefore, artists always work in daylight - colors are perceived better in a natural environment.

These experiments with a dress, sneakers look like some kind of illusory trick. I think this happens because the image is shown on a digital medium. The human eye reacts differently to the image on the screen. There are settings with which you can adjust the color rendering. Someone is more suitable when the color is more saturated, and for someone high contrast starts to hurt the eye.

Again, about cultural perception: you can draw a parallel with. For a person brought up in Japanese culture, a riot of color is typical, but not for a European. Many of my students complain about this exhibition as a painful experience: some even get headaches. We are just not used to perceive such intensity of colors.
