The Perifocal Glasses can be used for the greatest
length Of time, either BY day or night with perfect
CASE twhen selected to suit the state Of the eye and
never cause that gddncss Of the head or unpleasant
sensation to the eyes, that many experiences from
using the common kind, but tend to stssgfAem and
improve the sight; as will be seen by tho numerous
testimonials from those who have used them, which
can be examined by calling as above. We ask par

PHLADELpHIA, JMGreA ], l043
have recommended the Perifocal Spectacles to sev
eral patients, and have received from most Of them
warm encomiums upon the article. They assert that

is apt to be the case with the double convex Spsc-
tacles, while the command Of the eyes over the OBJ
jects Of vision is much greater. This corresponds
with the opinion any optician would form ftoin his
knowledge of the principles upon which thoae Glass
es are adjusted-so as to converge tho rays conlng
from different quarters to the same foca1 distance.
The eyes can be turned to = eouidBrabls extent,
