What if your lens of your eyes are a bit too strong and your eyeball is a bit too long?
myopic or nearsighted.
What is the diffrence between nearsightedness and farsightedness?
Nearsighted eyes, or myopia is caused when the eyeball is too long. The light rays focus in front of the retina causing images at further distances to become blurry. The nearsighted person can see objects close to them well, but things like road signs and small writing may be difficult. Farsightedness is called hyperopia. It is caused by the eyeball being too short. The light rays focus behind the retina causing all objects close to the person to become blurry. Farsighted people can only see things further away and objects up close are difficult to focus on.
What causes short sight and how it can be fixed?
Myopia, or near-sightedness, is caused because the eyeball is too long in relation to the focusing power of the lens onto the retina. This causes the image to be focused at a point in front of the retina rather than on top of it. There are two ways to correct this: corrective lenses (eyeglasses or contact lenses) or surgery.
How do glasses help short sighted people?
Short sighted people are not helped by lenses or anything else. Except the consequences of their short sightedness. I think you mean near sighted people. The eye is a lens and focal point system. The focal length of the eye can be manipulated by flexing muscles in the eye socket to change the distance between the lens and the back of the eyeball. A near sighted, or even a far sighted, person has an eyeball that is too long or too short for the lens, and therefore the image produced by the eye's lens is focused either in front of or behind the back of the eye. A lens, either in a pair of glasses or a contact lens, can assist the eye by effectively pre-focusing the image that enters the lens of the eye to a sharpness that can be accommodated by the focal length of the malformed eyeball, focusing the image sharply on the back of the eyeball. - wjs1632 -
