SOMETHING ABOUT GLASSES

SPEOTACLEs being essential to the
proper exercise and preservation of
vision, they should be treated as care
fully and rs scientifically as the Eyes
themselves. A knowledge of the proper
Glasses to be used involves a scientific
test of the eye to ascertain il there IS
any acuteness of sight, any disturbance
of accommodation, of whatever cause.
1t involves the nature of the patients
work, whether by day or night,
whether both eyes are equal in focus,
whether the pupils are of the same size
and dilate and contract in harmony,
whether the cOrnea is equal in all its me-
ridians, whether the muscles are equal
in length and power, whether the eyes
set In the same axis, whether they move
together, and whether they are bullying
or deep seated. The mere peddler of
Spectacles may be we'll up in the mystic
ries OF n salesman, and the best village
clock maker may know all about the
measure of time, but no dealer in Spec
tacles, unless acquainted with the ana
tomical structure of the eye, and of the
diseases and malformations of it's parts,
is competent to distinguish the exact
| uses and abuses of Glasses. and give as
surance that the Spectacles he sells will
| be ben eficial, and not injurious, to the
wearer.
The Oculist's science embraces the
cure of all diseases, injuries and abnor-
nal conditions of the eye. He makes
| the diagnosis, and the best Opticians
| follow his directions in setting the
| glasses in the proper frames, as to dis
lance from center to center of pupil,
| focus, axis angle, curvature, base and
apex. just as the intelligent Druggist
compounds prescriptions prescribed by
tho Physician. The terms, therefore, of

| A. b. Barker, NJ. d., now of IndianapO-
| lis, who has, for twenty-five years, made
speciality of Eye troubles, asserts, and
| he will be cOrrobOrated by every reputa-
BILE Oculist, as well as by the daily rec
ords of Eye Infirmaries, that the wrong
and nOn-use of glasses produce not only
more than One-balf of all the eye dis
eases, but are also productive of serious
| nervous disturbances. If the lenses of
| the Spectacles are not accurate, the
| slightest variation from the true axis
aud curvature will interfere with refrac-
ton, causing SQUIRTING and CATARACT,
| and subjecting the wearer tn dizziness,
headache and depressed spirits.
| Whether failure of vision is from age,
| injury, Overwork, weakness OF the
nerves, the muscles, or from malforma-
| ton, DR.. Barker is prepared to furnish
| Glasses with a written guarantee that
| tHcy are us IepTtScHtttt, anu uuupltu
| exactly for the purpose needed. The
material he uses is the best result of Art
and Science. the crystals being of high
| degree of polish they absorb all pris-
1 matte cOlOrs, admit only white, reflect
chlorific and exclude chemical rays, and
are of extra density, hence there is no
dizziness, objects are seen in their nat
| ural color, the eye is kept cool and ena-
bled To work indefinitely on black with
out fatigue, and they are exempt from
| scratching or DETACHMENT. The frames
| are not neglected.; the DR.. fits them care
| fully to the patients, for even the slight
est obliquity or fitting of the glasses
lessons their beneficial effect-to this
end, after examining tho eyes aud test
ing the vision, he measures from temple
to temple. from point of nose to end of

If the eyes set deep the frame is adj
