Hyperopia or Long sightedness, is a common vision problem, affecting almost a fourth of the population. People with hyperopia can see distant objects clearly but have difficulty seeing objects that are near.

Long sightedness or hyperopia, occurs if a persons eyeball is too short or when the cornea is too flat when compared to the normal eye. The light entering the eye focuses behind the retina, instead of directly on it hence close objects look blurred.

Young people with mild to moderate hyperopia are often able to see clearly because their eyes can adjust, or accommodate to increase the eye's focusing ability. However, at later years the eye gradually loses the ability to accommodate and blurred vision becomes more apparent.
