Nearsightedness Nearsightedness, also known as myopia, is the opposite of farsightedness It means that with your uncorrected natural vision, you have difficulty seeing at a distance This happens when the eyeball is too long Because it is longer than normal, light cannot focus properly through the lens and corneaPeople who have farsightedness (also known as hyperopia) have the opposite condition—close objects appear out of focus while distant objects are clear Farsightedness occurs when the eyeball is too short, causing light rays to reach a point of focus beyond the retina Farsightedness can also be treated by eyeglasses, contacts, or corrective Farsightedness makes it difficult to see objects that are closeup Nearsightedness makes it difficult to see objects from a distance Farsightedness occurs due to an imperfection in the eye and is usually genetic Nearsightedness occurs because of any number of factors and has many different degrees of severity
