As in any other life conditions, areas and spheres, people have also developed wrong and false views regarding vision. In this article, we will dispel the most common myths that have developed in this direction.


Reading in low light damages the eyes

Misconceptions about vision

From childhood, many of us probably remember the menacing shouts of our parents: “Don't read in the dark. Ruin your eyes." To the delight of many children who love to read in insufficient, from the point of view of their parents, lighting, we inform you: your moms and dads are wrong. According to the American Academy of Ophthalmology, "Reading in low light is no more damaging to the eyes than photographing in dim light is damaging to a camera." The only trouble that can come from reading at dusk is the headache from having to strain your eyes.


Carrots are very good for the eyes

Misconceptions about vision

Carrots are believed to be good for the eyes. The usefulness of carrots is explained by the fact that it contains beta-carotene, which in the human body turns into vitamin A, which is necessary for the retina of the eye. I must say that in the complete absence of this vitamin, the human eye does not adapt to the dark. However, it is not at all necessary to absorb carrots in kilograms in order to get the right amount of vitamin A. The fact is that there are large reserves of beta-carotene in the liver, which are easily replenished with a variety of products. Therefore, fears that vitamin A will not be enough and vision will deteriorate from this are in vain.


Sun exposure without sunglasses is bad for your eyesight

Misconceptions about vision

The opinion that sun exposure without sunglasses is harmful to vision is also not true. Sunglasses in the city are more decoration than protection. Perhaps they are really important only in the mountains, where excessively bright sunlight is enhanced by the effect of reflection from the snow.


Myopia is hereditary

Misconceptions about vision

Those who think that if parents wear glasses, myopia will certainly be inherited by the child are also mistaken. This is nothing more than a myth. It would be more correct to say that it is not the disease itself that is inherited, but the peculiarities of metabolism and the structure of the eyeball. In some people, the naturally weak outer shell of the eyeball (sclera) does not offer proper resistance to the growth of the eye. And work at close range (reading, writing) contributes to this growth, which means the development of myopia.


Computer or TV damage your eyesight

Misconceptions about vision

Ophthalmologists often argue on this topic, but most agree that for most people this is not the cause of poor vision.

On the other hand, more and more people complain of symptoms such as dry and irritated eyes, headaches, eye strain and difficulty focusing after prolonged screen time. This phenomenon has been called computer vision syndrome, which can be exacerbated by frequent focusing on the small screen of a tablet or phone.

Experts recommend using the 20-20 rule to eliminate the effects of time spent in front of a computer screen or TV. It sounds like this: every 20 minutes, take a 20-second break to look at a distance of about 6 meters.


Wearing glasses for a long time only worsens your vision

Misconceptions about vision

According to the myth, wearing glasses for disorders such as nearsightedness, farsightedness and astigmatism can weaken or impair vision. This is not true, nor is it possible to damage vision by wearing glasses with strong diopters, although this may cause temporary tension or headache.

The statement that if you constantly wear glasses (or contact lenses), then they change the physiology of the eyes, is nothing more than a myth. If the glasses are chosen correctly, they will not spoil your vision.


In space, human vision remains the same as on Earth

Misconceptions about vision

Scientists have found that vision deteriorates in space, but they cannot explain this phenomenon. A study of seven astronauts who spent more than six months aboard the International Space Station found that all experienced blurred vision while in space and several months after the space mission.

The researchers suggest that the cause may be the movement of fluid to the head, which occurs in microgravity.


Visual impairment is the result of weakness of the eye muscles

Misconceptions about vision

In fact, the muscles around the eyes are 150 to 200 times stronger than they need to be to function properly. These muscles rarely weaken. On the contrary, from constant tension they become excessively strengthened, which interferes with their natural flexibility and mobility – they become constrained and inactive.

Over time, certain habits and patterns of behavior develop, as a result of which some eye muscles become stronger and more consistent than others. But the problem is not in the muscles themselves, but in habits. By changing habits, the eyes can be retrained. And such symptoms as nearsightedness, farsightedness, etc. will weaken or disappear.
