Normal Vision
An eye that has normal vision is able to focus
light from distance objects directly onto the
retina, the "film" in the back of the eye. These
clear images are transmitted to the brain. Our
eye has a lens that is able to adjust its focusing
power. When the lens is "relaxed," light rays
from distance objects focus properly on the retina.
To see near objects, the lens has to "contract"
for incoming light rays to focus on the retina.
Sometime at or after the age of 40, our ability
to "contract" our eye's lens starts to decrease.
Prebyopic individuals notice that they cannot
see objects up close anymore. This is the normal
maturation of the eye. If someone has not worn
glasses before, individuals have to start wearing
reading glasses for near vision. An individual
already wearing glasses for vision correction
will likely have to wear bifocals.
