¨Presbyopia is brought on by aging
and
occurs because the crystalline
lens
of the eye becomes less flexible
as
well as the ciliary muscle loses
strength
¨When a presbyopic eye is trying to
focus
on something near, the light
gets
focused on a plane behind the
retina
¨In my demonstration, I did not allow
all
the water to enter the lens as the
image
was placed near
¨The result is a fuzzy image on
the
screen
