Hyperopia Hyperopia, or far-sightedness, is the opposite of myopia. Here, you eye is too short or your cornea is less curved. Consequently, light rays entering your eye fall behind the retina. This results in blurred vision which is worse at near distances than far. Astigmatism Astigmatism occurs when your cornea is shaped like a football with two different curvatures.
Images appear blurred or ghost-like because light rays are refracted unequally.
In extreme cases, images both near and far, appear blurred. Many people who have myopia also have astigmatism. Presbyopia Presbyopia is the inability to focus the eyes at near. Presbyopia generally begins around age 40 as the lens inside our eye loses its ability to change shape. Presbyopia can be quite troublesome if one has to work at a computer all day long.
