Whenever
we use our eyes to see something up close, it
flexes the lens to create a focal point to use
as reference for the object being seen or read.
As a result of aging, the lens loses its elasticity
and the focal point shifts to behind the retina
rather than its normal placement at the rear of
the eye. This is the Presbyopia condition referred
to at the top of this page and can be easily corrected
with the CK treatment.
