Medicated SpeCtaCles.

recently been extensively advertised IN the
state as wonderful scientific discovery, and it
has been claimed that the glasses are medi-
Gated in such a manner as to preserve and in
some cases restore the sight 1t is said that
these chemicals soften the light to the eye and
keep the glasses bright and cool. And other
virtues are claimed for this wonderful discov-
cry. Several persons who have heard of it
have called our attention, asking for informa-
ton on the subject. five had have answered
right away we should have used an expressive,
if not polite phrase ''bosh," but in justice to
all concerned, we thought it desirable to make
inquiries of our medical men, and we there
fore called upon them, putting the question
plainly. as to whether glass could be medicat-
ed in any way to be advantageous to the hui
man sight, and the answers were as follows
DIR. f. Herff: Certainly not. There is no
m. ans of indicating glass to be of advantage
10 the sight other than that of coloring the
glass and of subduing the light.
DR.. Adoph Iertf, who was with his father,
was QSCluSulS vi lilC same opiiiloh.
DR.. Shepherd considered that such thing
was impossible and added significantly, ''the
more chemical matter there is in the glass
other than the ordinary coloring matter, the
worse for the eyes,
DIR. Edward Bennett knew of no way in
which medicated matter could be introduced
into glass, and if it could be, the vitrfying
process would certainly destroy it. He, of
course, excepted the ordinary glasses for sof-
tening the light.
DR.. S. T. Lowry considered that there was
no known law in physic or optics by which
glass could he medicated in such way as to
be of service to the sight. Glass can be.col-
ored in the ordinary way and be useful in
modifying the intensity of the light
DR.. J. Jones, in reply to our interrogation
answered decidedly, no There have been
cases where the sight has been improved by
the use of colored glass to modify the light,
but medcated glass is an impossibiliy.
Mr.. !. w. c. Love, who has been an opi
clan for eight years, and practiced opthalmics
for four years as specially states,
cmphatically, that glass cannot be med
icated to preserve or restore the sight
He has examined the so-called medi-
Gated spectacles and the only difference he
finds in them is in the price, the indicated
spectacles being charged almost 100 per cent.
more for than the ordinary spectacles of the
SAM quality.
This is the testimony Of gentlemen who, by
their profession and experience are qualified
to give an authoritative opinion upon the value
of medicated spectacles, and, Judging from it,,
we are obliged to inform our correspondent
that since the day when worthless spectacles
were imposed upon Moses, as recorded in the
greater hoax in the spectaces way. We do
not say that the medicated spectacles are not
fair. ordinary goods, but we declare that in
our opinion, based on medical authority, there
is no grounds for saying these glasses are
medicated and that such statement is an i'm
posture on public credulity which ought to be
exposed.
