What's the difference between farsighted and nearsightedness?
Both are refractive conditions, meaning that they are problems related to how the light is focused as it enters the eye. Ideally, as light enters the eye, without any additional effort, the light would be perfectly focused onto the inside lining of the eye which detects the light, called the retina. The brain would than see a clear view of the world. This person would not need glasses for the distance.
If a person is farsighted (hyperopic), the optics of the eye are too weak (or the eye is too short), and the rays of light would focus behind the retina, causing a blurred image to be on the retina. This person in general would see better at distance than near, or be "farsighted."
If a person is nearsighted (myopic), the light rays focus in front of the retina because the optics are too strong (or the eye is too long). This also causes a blurred image to fall on the retina. This person would see better at near, or be nearsighted.
