1.-THE demand for artificial eyes, "
said the proprietor of glass eye
factory in New York to writer re-
Gently, twas larger during the last
two years than I have ever known
it to be, and / have been engaged in
the manufacture of the article in
question for the past quarter of a
century. Last year we sold 50, 1000
artificial eyes, or an increase of
1000 over the previous year. Prior
to that our sales would not exceed
90, 900 annually. The recent demand
indicates that more people are wear
ing glass eyes than formerly, and
one of the chief reasons for this is
that the false articles are sold cheap
er and are made to resemble the
natural organs more perfectly now
than ever before Hence the poor
who are compelled to wear glass
eyes have little difficulty in obtain
ing them, and rich people are less
sensitive about wearing the artifi-
cal product when necessary. Ten
years ago an ordinary glass eye cost
from Sc ITO 81, while those made to
order with.the pupil and, the cornea
carefully colored, sold anywhere
from $12 to $50 Competition has
cut these prices down, until now an
ordinary eye sells for SIS and the
finer grades are worth from SO to
$50, according to finish.
More gray eyes are manufacture
ed than any other color, then comes
the blue and next the brown eye.
The call for black eyes is quite rare.
They are only made to order and
are seldom if ever kept in stock.
Ophthalmia hospitals are the largest
consumers of false eyes. These in
situations buy in quantities, and
naturally obtain their supply at re-
duced rates, They generally pur-
chase the ready made eyes, which
are used on poor patients who are
not in financial position to be fas-
tidious either as to the quality or
finish of the article. We have hun
dreds of customers scattered all over
the country, for all of whom we
keep duplicates, ready to ship when
ordered. The best glass eyes do not
last for more than year, owing to
the action of such moisture az the
tear, the acids of which affect the
enamel. roughen the edges of the
surface, and very often cause pain
full irritation of the eyelids.
"The process of manufacture is
interesting. In it's initial stage the
eye is a long, slender stick of en-
amel, made of perfectly transparent
and fusible flint glass. This is put
into crucible and exposed to great
heat Now the globemaker places
the enamel over blowpipe supplied
with air, which is pumped by al
machine into a huge cylinder and
stored under water pressure. Then
under the careful manipulation Of
the workman the enamel tube is
formed into an oblong globe, just
the size and shape of the human
eye. Next it passes into the colcring
room, where a correct tint is APP
piled to the summit of the globe,
and this is gently heated by small
fame and continuously rotated. |
When it has assumed the correct
form of the iris, more coloring
matter is added to represent the pu-
pill, and it is then covered by thick
layer of crystal to form the cornea. |
This done, the eye is cooled and
sent to the cutting room, where it |
is formed into small hollow oval, |
with irregular edges. These edges
are again heated and the eye allow
ed to cool slowly. This tempering
process toughens the enamel and
renders it less liable to break. The
finish work consistsin polishing the
eye, and when this has been COM
pleted it is ready for the market. -
