Hyperopia is also
known as farsightedness, longsightedness or hypermetropia. It is a common vision
problem. Affected people have greater difficulty seeing near objects than
is a common visual problem where the
affected person is unable to see near objects clearly. Almost one fourth of the population is
affected by hyperopia. Hyperopia is typically caused due to genetic factors. It is often present from birth.
Hyperopia occurs if a personís eyeball is too

entering the eye focuses behind the retina, instead of directly on it, hence

A person with hyperopia typically experiences
eye strain and fatigue while trying to focus on near objects.
Young people with mild to moderate hyperopia are
