What
is it?
Some people
develop a problem of having to hold books far in order to read
comfortably. These people suffer from a condition called hyperopia,
more often referred to as farsightedness.
Hyperopia
is a condition in which near objects appear blurry. The patient
may see far objects well, but the close objects are just a blur. The
lens in the patient's eyes cannot focus near objects to a point correctly.
After much straining, a farsighted person's lens will not hold its
shape to converge the light to a point in the back of the retina.
In farsighted people, the bulge in the middle of their eyes tends
to be rather flatter than normal eyes.

to a point in farsighted eyes.

What
causes it?
Many different
factors will cause hyperopia, such as diseases or injuries. Any type
of refractive error may be a sign of a bigger, more serious disease.
The eyeball
may be too short in shape, so light is overfocused.
Symptoms
1.
holding
books far to read
2.
not
being able to see small print well
Treatment
Convex
glasses or contacts
will improve this condition to 20/20 most of the times. They will
help the eye lens converge light to a point in the back of your eye,
called the macula.
LASIK
laser eye surgery has also lead to almost permanent eye correction.
By this method, corneal tissue is removed from the corners of the
cornea in order to make the bulge more apparent.

a convex lens can re-focus light to a normal point on the retina.
