SMALL ERRORS OF LONG SIGHT For the patient who suffers
with a low error of long sight the need for glasses
is often difficult to understand mainly because,
unlike a short sighted patient or very long-sighted
patient, they often enjoy good vision at both
distance and near without wearing spectacles.
Understanding how the eye works and why glasses
are needed for such errors, is vital for a person
since without a little knowledge sufferers are
unlikely to get the most out of their glasses.
In extreme cases, because glasses for short sight
don't always make things clearer, some may even
feel their optician has "Sold" glasses
simply for commercial reasons. We have produced
this Fact Sheet to ensure that our patients with
small errors of long sight are fully informed
why they need glasses and how to get the very
best from them.
To understand long sight there are certain basic
facts to appreciate.
1.
The eye is like
a camera - the internal crystalline lens has
to be focused on the object in view to see
clearly.
2.
Normally sighted
or not the muscles in the eye, without you
feeling anything, are automatically adjusting
the focus of your intra-ocular lens all day
long just like an auto focus camera.
3.
The internal
focusing muscles work in one direction only.
They can correct, or partially reduce an error
of long sight, but have absolutely no effect
on short sight.
How is it that a person who has a small error
of long sight can still see clearly?
Imagine your eye to be just like an auto focus
camera. Immediately you open your eyes after
sleep the brain registers that distance vision
is not as clear as it ought to be. Immediately,
and without any sensation the automatic nerve
system starts "pulling" the eye's
internal lens into the correct curvature to
give you a sharp, crisp image.
