Farsightedness

Farsightedness, also known as hyperopia, is an eye condition that results in blurry near vision. People who are farsighted have more trouble seeing things that are close up than those that are far away. Light passes through the clear cornea at the front of the eye and is focused by the lens onto the retina's surface, which is the lining of the eye's back that contains light-sensing cells. Eyeballs that are too short from front to back are seen by many people who are farsighted. These improvements have caused light entering the eye to be focused too far back, behind the retina, rather than on its surface. One eye may be more farsighted than the other in a person with this condition. However, some children with the eye changes characteristic of farsightedness do not experience any blurring of their vision or other signs and symptoms early in life. Children with a high degree of farsightedness, also known as hyperopia, are at a higher risk of developing other eye conditions, particularly "lazy eye" and eyes that do not appear to be in the same direction. Presbyopia increases as the eye's lens becomes thicker and less flexible with age, and the muscles surrounding the lens weaken. Presbyopia is caused by a different mechanism than hyperopia and is classed as a distinct disorder by some people who refer to it as "farsightedness. ".
