the inner surface Of the cavity of the
eyeball to form the retina. The crys- |
talline lens and its ligaments divide
the eye into two chambers, the anterior

Der is very small and lies between the
cornea. or outer surface of the eye,
and the lens. 1t is filled with Il fluid
similar to tears, the aqueous humOr.
The pOsterior chamber is large and
constitutes the cavity of the eyeball
behind the crystalline lens. 1t is

Is a circular, muscular curtain. an
extension of one of tie coats of the
eyeball. which by dilating or contract
ing controls the amount Of light ad-
mitted to the interior of the eye. The
shape Of the crystalline lens is also
controlled by the little ciliary muscles.
Varieties Of Defective Sight.
Astigmatism is caused by an in
equality in the curvature of the cor
nea. This may occur in any meridian
of the eye and requires glasses that
will so bend the rays as to correct the
DETECTION caused by the irregular sur
face.
Observation-Disclosures is caused by
an unduly long eyeball from before
backward The rays of light meet be-
fore they reach the retina. The cornea
in such cases is usually abnormally
convex.
Farsightedness.- is caused by q
short eyeball from before backward.
The rays of light fail to meet before
they reach the retina.
In both of the above conditions a dis
torted image Is formed. and glasses
are required either for near or distant
vision.
Importance Of Proper Glasses.
The degree of injury that results
from errors of refraction depends upon
the temperament and constitution of
the error. Just as little tobacco or
alcohol will in some subjects produce
chaos In the nervous system so will a
slight refractive error in a person of
unstable nervous organization cause Il
profound disturbance of the general
health.
When a refractive error exists the
ciliary muscles endeavor to correct II
