Hyperopia is sometimes called long-sightedness. Hyperopic people usually have good distance vision but have to make extra focusing efforts for near vision work.
Hyperopia is usually caused by the eyeball being smaller than normal. This means that the light cannot focus on the retina (it would focus “behind” the back of the eye). When the eye is young enough and has strength to increase it focusing power good near vision is possible but will generate eyestrain. When this is not possible, near vision will become blurry.
We encourage you to consult your local eye care specialist for more information.
