Nearsightedness or myopia is when there’s difficulty with eye focusing. Things at a distance will be seen as blurred causing troubles with driving which imposes a high risk of danger.
Two parts of our eyes are involved with myopia.
First is the cornea which is the clear covering on the eye’s front part. It covers the pupil which is the eye’s opening. It also covers the iris which is the eye’s colored part. And lastly, it also covers the eye’s anterior chamber which is the eye’s inside that is filled with fluid. The cornea is like the eye’s window which controls and focuses the light that enters the eye.
Second part is the lens. The lens changes the eye’s focal distance by changing its shape. It focuses the light rays passing through to create a clear image.
Myopia is a result of the eye shape being not smoothly and regularly curved than it is supposed to be. Eyeball may be longer than normal or the cornea maybe curved too sharply.
Cells on the retina receive and convert light rays into electrochemical impulses which are sent to the brain through the optic nerve.
Myopia causes light rays to bend inaccurately thus focusing images in front of the retina. Images must be focused directly on the retina’s surface, and not in front of the retina.
People with high myopia are at potential risk of developing detached retina, glaucoma and cataracts.
Myopia can be confirmed through an eye examination. In order to correct the blurred images of things at a distance, you will be prescribed with the standard prescription eyeglasses or contact lenses. There is also a surgery called refractive surgery which helps correct these blurred images without the use of eyeglasses or contact lenses.
If you are experiencing nearsightedness, have your eyes examined so we can help you.
