It is normal for most eyes to be long-sighted (hyperopia) at
birth.
This usually reduces as the eye grows to full adult size during
adolescence. It is then in the teens that short-sightedness
(myopia) tends to develop, if at all.
After a relatively stable time throughout the 20's and
30's, another significant time for change begins in the 40's. This
involves a gradual loss in the ability to finely focus the lens
inside the eye. The result is a totally normal and expected change
called "presbyopia", which continues into the 60's.
After 60, the eye will tend toward less long-sightedness or more
short-sightedness as the inner part of the eye lens hardens.
Sensitive vision drops and the retina's fine discrimination of
colours is dulled. By 70 most eyes show signs of cataract and the
older, harder, clouded eye lens scatters light so that glare often
becomes more of a problem.
