Hyperopia, or farsightedness, is a common vision problem. Hyperopia occurs when the eye is shorter than normal or has a cornea that is too flat. As a result, light rays focus beyond the retina instead of on it. Generally, this allows you to see distant objects somewhat clearly but near objects will appear more blurred.
Farsighted people sometimes have headaches or eyestrain, and may squint or feel fatigued when performing work at close range.
What Causes Hyperopia?
Farsightedness is usually inherited. Most children are farsighted, yet they do not experience blurry vision. With focusing (accommodation), children's eyes are able to bend the light rays and place them directly on the retina. As long as the farsightedness is not too severe, hyperopic children will have clear vision for seeing objects at a distance and up close. As the eye grows and becomes longer, hyperopia lessens.
People, however, sometimes confuse hyperopia with presbyopia, which also involves difficulty with seeing up close. But presbyopia has a different cause and occurs after age 40.
There is no best method for correcting hyperopia. The most appropriate correction for you depends on your eyes and your lifestyle. You should discuss your lifestyle with your eye doctor to decide which correction may be most effective for you.
Eyeglasses or contact lenses can correct farsightedness to change the way light rays bend into the eyes. Depending on the amount of farsightedness you have, you may need to wear your glasses or contacts all the time, or only when reading, working on a computer or doing other close-up work.
Refractive surgery, such as LASIK or PRK, is another option for correcting hyperopia. These surgical procedures are used to correct or improve your vision by reshaping the cornea, or front surface of your eye, effectively adjusting your eye's focusing ability.
