Normal Vision
Those
with hyperopia, or farsightedness, report difficulty
seeing objects up close. In normal vision, light
is properly focused through the cornea and lens
to form sharp images on the retina. The retina,
the "film" of the eye, transmits these
sharp images to the brain. In hyperopia, the images
are focused behind rather than directly on the
retina.
This is because the cornea is too flat relative
to the length of the eye. This results in blurry
near vision. The eye is able to compensate in
these situations to allow your distance vision
to remain sharp, hence the term "farsightedness."
Young eyes can often adjust the focusing power
of the internal lens of the eye to compensate
for this condition early on. That is why the condition
often does not present until later on in life.
Hyperopia is different from presbyopia, the difficulty
people have seeing up close after the age of 40.
