Myopia, commonly known as near-sightedness, is a condition in which a person can see better near than far, without correction. Hyperopia, or far-sightedness, is the opposite—the person can see better far than near, but may have enough focusing ability to see near, however, frequently with eyestrain. Astigmatism is a condition in which the front clear cover of the eye is shaped like an egg or football, and affects vision at all distance. Presbyopia is the loss of focusing ability at near vision, with correction, and occurs in our early 40’s A person may have one or a combination of these eye problems, though an eye can’t be both near-sighted and far-sighted. However, it could be near-sighted and have presbyopia.
