Hyperopia 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 person’s 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.
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
often able to see clearly because their eyes can accommodate (adjust) to
increase the eye's focusing ability. However, in later years, the eyes gradually
lose their ability to adjust the focusing power and blurred vision becomes more
apparent.
Glasses or contact lenses can be used to correct
hyperopia. Surgical techniques are also available for correcting
long-sightedness.
