Hyperopia, or farsightedness, is a common vision problem affecting about 1 out of every 4 people in the U.S. The term Farsighted and Nearsighted often confuse people. If you think about it, it really describes the condition. Think of this as 2 words: "far" (and) "sighted". It simply means that you can see at distance (far). People with hyperopia can usually see distant objects well but have difficulty seeing objects that are up close.
Farsighted people sometimes have headaches or eyestrain, especially when reading and doing other near work, such as working on the computer. They may squint or feel fatigued when performing work at close range. If this occurs to you while wearing your glasses or contact lenses, you may need an eye exam and a new prescription.
Farsightedness occurs when light rays don’t focus correctly onto the back of the eye (retina). It is common for infants to be hyperopic and for this to change within the first few months of life.
Hyperopia is often confused with presbyopia, which also involves difficulty with seeing up close. Presbyopia has a different cause and occurs after age 40.
Eyeglasses or contact lenses can compensate for farsightedness because they change the way light rays bend into the eyes. Orthokeratology is a way that we can change the curvature without surgery. If your glasses or contact lens prescription begins with plus numbers, like +2.50, you are farsighted.
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.
