sons in the Country, or abroad, may be suited
by sending the Glasses they last wore, or
piece of them, or word if they are the first they
have required, or the length of time they have
worn glasses.
1t being fact, that bad or improper
Glasses tend greatly to injure the eyes,--the
subject demands some few remarks.-The eyes
Of many persons have been much injured by
wearing the glasses Of older persons, because
they were at hand; also by wrong choice of
Spectacles, and purchasing them of Pedars
and Others who are unacQuainted with
the article, and unable TO adapt the va
rious glasses to the different eyes; Others from
prejudice, or advice from persons whose eyes
do no; require the aid of glasses, have refrain
ed, without rejecting on the consequences of
using glasses as long as they could possibly do
without them, have strained and hurt the
nerves of the eyes almost beyond remedy
The truth is, that the sight is best preserved
by making use OF proper Glasses as soon as the
sight begins to fail, which will be discovered
by making pen, threading needle, or read
ing by candle-licht. Glasses timely used will
relieve and preserve the sight, and continue the
health OF the eyes. The eyes need guard at
particular times. as we'll as the head. The eff
feet of bright sun on the snow, of dust, or
cold winds, has distressed many eyes that
would not have suffered, had Green Glasses
or Goggles been used, as occasion required.
As to the benefit those receive whose eyes
required the aid Of SpectacIes, il SO great and
general. that it would be mere mpertnence to
expatiate upon it and many other invaluable
blessings result from this art OF improving the
sight, which the experience OF mankind has
long since eyincei-many could not be with
out them and not be miserable.
