Hyperopia or Farsightedness is a common vision problem affecting many people. People with Hyperopia can see objects at far distances very well, but these same people have trouble seeing the same objects when they are at close distances.
Farsighted people sometimes have headaches caused by eyestrain, and will also squint or feel fatigued during and after performing work at close distances. This vision problem occurs when light rays entering the eye focus behind the retina, rather than directly on it. The eyeball of a farsighted person is shorter than normal. Similarly, Presbyopia is attributable to physiological changes in the lens; however, Presbyopia is usually brought on by age. Corrective eyeglasses with convex lenses compensate for the refractive errors. Farsightedness can be corrected with glasses or contact lenses. Farsightedness can also be treated with refractive surgery.
