Debunking 6 Common Eye And Vision-Related Myths

The eyes are a very sensitive and important organ of the human body. Considering their delicate nature, people often tend to become too cautious. Their belief in certain myths leads to ignoring serious eye problems they might be suffering from. Here are six common myths related to the eye and vision that everyone should know.

Myth 1 - Crossing Eyes Leads To Permanent Damage

Strabismus or crossed eyes does not happen when you cross your eyes voluntarily. The muscles in your eyes allow movement of your eyeball in different directions. Strabismus occurs as a result of muscle damage, nerve damage, or uncorrected refractive error. So when you look up, down, left, or right, your eyes do not make your eyes permanently cross.

Myth 2 - Eyes Can Be Transplanted

It is thought that the whole eye is transplanted. This is not possible because your eyes are connected to the brain via the optic nerve. This nerve is made of millions of tiny nerve fibres. When these nerves are cut, it is impossible to reconnect them. So, when one talks of eye transplantation, it is the cornea, the central part of the eyes, that is replaced and not the whole eye.

Myth 3 - Sitting Close To Television Harms Your Eyes

You might be conscious of the light that is reflected by the television or computer screens. According to Harvard Health Publishing, blue light from electronic devices does not harm any part of your eye or increase the risk of macular degeneration. But this does not mean that staring at a screen is a norm. This might be a sign that a person has other eye conditions such as nearsightedness and needs glasses. Also, when you stare at screens for long periods of time your sleep and other aspects of your health get disturbed. Staring at screens without blinking can also dry your eyes.

Myth 4 - A Perfect Central Vision Means Perfect Eyes

An excellent central vision, aka 20/20 vision, can make you think that your eyes are in perfect condition. However, this does not eliminate the possibility of other vision-related problems, like imperfect night vision, side vision, and colour vision. Disorders like glaucoma or diabetic retinopathy, which take years to show symptoms, can harm your inner eye while your central vision remains intact.

Myth 5 - Reading In Dim Light Damages Your Eyes

You may be conscious of light while reading or doing a task. It has been widely said that reading in low light could damage your eyes. As a result, reading in high-intensity light is preferred.

However, the fact says otherwise. While reading in low light, you might experience some strain or fatigue in your eyes. This does not mean that low light is damaging your eyesight. However, you should avoid doing this for prolonged periods of time.

Myth 6 - Using Incorrect Glasses Will Damage Your Eyes

This is another common eye-related myth that people believe in. When you wear lenses that are either too high or low in power, you may experience discomfort, blurriness, and headache, which go away as soon as you take the glasses off. These glasses may not correct your vision but do not harm it as well. But for obvious reasons, you should wear glasses with the correct lenses.
