Myths and realities about vision

Certain myths about the eyes have circulated for so long that we usually accept them as truths.But believing in myths can jeopardize our vision.Here we present eight myths and realities about vision. Do you know which one is which?

The eyes can not be transplanted.

Reality. Nowadays whole-eye transplantation is out of medical possibilities due to the thread that connects the eyes to the brain. This connection is known as an optic nerve and can not be cut.

It is possible to get conjunctivitis only through someone who has it.

Fiction. Conjunctivitis is a condition that causes inflammation of the inner lining of the eyelids. It can be caused by any element that inflames the tissues, for example irritants, allergies or an infection.

Older people should not use their eyes too much or try to read the small print for fear of wearing down their eyes too quickly.

Fiction. Using the eyes does not cause or accelerate the loss of vision.

Using glasses daily will make your eyes weaken or suffer from lazy eye or amblyopia.

Fiction. The objective of vision correction is twofold: on the one hand, to provide a clear vision, and on the other, to provide visual comfort. Some eyes can see properly without needing to correct the vision but only making unnecessary effort. This can cause fatigue, discomfort and loss of visual acuity. The use of prescription glasses correctly will not accelerate in any way the anticipated and natural changes that your eyes will suffer throughout life.

The glasses change the shape of the eye.

Fiction . The glasses do not change the shape of the eye. With age, the eye naturally experiences slight changes in its shape, which may increase or decrease depending on the growth of the eye.

It is okay to look directly at the sun if you do it by squinting (“chipping”) your eyes a lot.

Fiction. UV (ultraviolet) light from the sun can cause burns to the cornea (which is known as photokeratitis) on the skin. In the long term, it can increase your chances of developing cataracts (clouding of the lens) and damage to the retina that can lead to total blindness. Sunscreens can protect your skin from overexposure to UV rays. Equally, appropriate eyeglasses can block UV radiation and protect the eyes safely.

The reddened eyes are the product of infections.

Fiction. Actually, most cases of itching (itching) and redness in the eyes are due to allergies or “dry eye syndrome”, which do not respond to antibiotics used for the treatment of bacterial infections.

The use of the wrong glasses can tire the eye, but it is not harmful.
