Farsightedness, or hyperopia, is a very common vision problem, affecting almost 25 percent of the population. Farsighted individuals can see distant objects very clearly, but have difficulty focusing on objects that are up close, like a book. Farsighted people will often squint or feel fatigued when performing work at close. This squinting or fatigue causes eye strain and often results in headaches and/or migraines.
Farsighted vision occurs when light rays entering the eye focus behind the retina, rather than directly on it. The eyeball of a farsighted person is shorter/shallower than normal. Many children are born farsighted, and some of them outgrow it as the eyeball lengthens with normal growth.
Farsightedness can be corrected with glasses or contact lenses to change the way light rays bend into the eyes. Refractive surgery, such as LASIK or CK, can also correct farsightedness.
Have a prescription and not sure if you are farsighted or nearsighted? If your glasses or contact lens prescription begins with positive (+) numbers, like +2.50, you are farsighted.
If you find yourself squinting at nearby objects while wearing your eyeglasses or contact lenses, you may need an eye exam and a new prescription.
