eya-sight is positively injured by them. If
We tamper with our eyes. and n,erpose
glasses between the cornea and the object,
re. modification and e.adius'ment Of the
parts within necessarily follow--anc when
this new arrangement has once been estab.
lished. it is no easy matter 10 restore the
organs TO their former primitive condition.
Age brings with it relaxation Of the ten.
sion of all the tissues, and the eye suffers
temporarily with the entire system, bu, soon
reacts, having within It's constitution a
principle Of adaptation, according to the cir.
cumstances, habits and condition of,he indi.
vidual. From forty fve TO fifty, period
when glasses are erroneousy supposed
indispensable, where they are resorted to at
all, although there be defective vision at
the former local distance, in reading for
example, the sight would soon begin 10 im-
prove, and finally, to all inlenls and purpo.
ses, in a majority of instances would be
re-estabished. 1t is law, and strange II
is that its indications are not more observed
that the eye, at every period of life, will
accommodate itself to the wants and me-
cessities of the individuals--provided 1t is
not arti6ciaEy derauged. Imperfect vision,
the evils of near.sigh,edness, and the MIS-
fortune of not seeing distinctly in old age,
were never heard Of as being universal till
opticians had become numerous. We DO
not deny the utility of spectacles after they
have been once re orted 10 but we per.
ftc,lv agree with DR.. Wallace in saying
that they are rarely necessary. Near
sighted children are often kep, in that state
through life by being early furnished with
concave spcctacies. Withhold them alto
| sether, and eye would, in exact obedience
to the laws Of its organization, adopt itself
to the labor required. Bu, when the gas.
| ses are once put on, they must ever after be
retained.
Incalculable injury has been the result OF
the fashionable folly Of wearing quizing
glasses. Both gentlemen and ladies', in the
spring tide ofyou,h. whose eyes are without
single defect, peep through these useless
appendages ofsupposed gen,ilty, till a per.
manent and incurable difficulty ensucs
which time has no power to correct, which
consists in a want ofagreemen, in the focus
Of Two organs. Unless the surface on which
the image impinges on the retina perfectly
agree in both eyes, there will be distorted
and indstinct vision--such as this kind OF
object or prospect glasses produces.
I'VE know gentleman who four or fve years
ago began to experience some difficulty in read.
ing by candle light, and found it necessary, even
in the day, to seek strong light to make PEN
Hoping that, by use, the eye would accommodate
itself to the physical changes brought about BY
advancing age. he submitted to the Inconvenience
as well as he could for year or more, when he
procured a pair Of spectacles; whic however,
he very rarely used except in making pen, while
his daily occupation required hin. to read much
the greater part Of it printed with small type
In doing this he found it necessary for some time
to seek favorable light, and he was careful to
hold his book or paper as near his eyes as he
could without straining them SO much as 10 give
pain. The result is that he has laid his
spectacles aside and has not opened them for more
than six months. He makes pen in ordinary
light without difficulty, and reads the finest
print with ease at little If any more than the
common distance from the eye. The eye does
not always accommodate itself to the defiance
as readily now as it did in early lifc. But it il
now painful to read with the book as far removed
as was most agreeable twelve months since
How long this favorable change may last, time
only can determine. 1t is probable tho same
effect would not have been produced had the
eyes been less exercised in reading fine print.
