Essay On Eyeglasses

Introduction:

Eyeglasses come in many different shapes, designs, sizes, and colours. Glasses are used to help people see better, and there are many different problems with eyes which prevent people from seeing as clearly as others.

On top of your eyeball, there is a clear tissue that helps the eye focus, which is called the cornea. On your eye, there is also the iris, which is the coloured part, the lens, which also helps your eye to focus, and lastly the retina, which is at the very back of the eye. For an image to be focused sharply on your retina, your eyes need to bend light rays. The better the your retina notes down the image, the more likely your brain will interpret the image, and it's more likely that you will see the image clearly. Another word for bending light rays is refracting. If a person has a vision impairment, often, it's a refractive error.

There are four types of refractive errors. They are myopia, hyperopia, astigmatism, and presbyopia. (Tidy, n.d.). Glasses and contact lenses can easily correct

Long-sighted people have eyes that are shorter than normal eyes, which means that the light will focus behind the retina. As a result, long-sighted people will have to focus more than they should, especially on things that are up close to them. (“Long and short sightedness,” 2000)

Hyperopia symptoms vary from person to person. Some include headaches, eyestrain, and squinting.

Like myopia, hyperopia can affect both adults and children. It affects about 5 to 10 percent of Americans. And like myopia, people whose parents have hyperopia, may be more likely to get the condition.

Solution:

The most common solutions to near and long sightedness are eyeglasses and contact lenses. Glasses can correct your vision because they allow the eye to focus light in the right place on your retina, this is the spot that produces the clearest
