Varieties of Defective Sight.
Astigmatism is caused by an in
equality in the curvature OF the cor

OF the eye and requires glasses that
will 80 bend the rays as to correct the
detection caused by the irregular sur

Nearsightedness.- Ia caused by
an unduly long eyebsll from before
backward. The rays OF light meet be-
fore they reach the retina. The cornea
in such cases is usually abnormally
convex.
Farsightedness.- This is caused by a
short eycball from before backward
The rays OF light fail to meet before
they reach the retina.

Importance of Proper Glasses.
The degree of injury that results
from errors of refraction depends upon
the temperament and constitution of
the individual as we'll as the extent OF
the error. Just as a little tobacco or
alcohol will in some subjects produce
chaos In the nervous system so will a
slight retroactive error IN person OF
unstable nervous organization cause a
profound disturbance OF the general
health.
When a refractive error exists the
ciliary muscles endeavor to correct II
by altering the shape OF the lens. I'm
less the error Is extreme the effort Is
usually successful, and the patient
thinks he has good eyesight. But q
condition OF tension exists in the mech
anism of accommodation which vii
