Now, while these changes have in real
ity been going forward since childhood,
they do not Under ordeEofdiiary circum-
stances, make themselves sppreciably felt
until about the fortieth year. Owe speak

that and the fiftieth year most individu-
ais experience difficulty in recognizing
small objects, especially under bad illu-

and turned SO as to have the light fall
upon it most advantageously,. This sort
of thing growing from bad i6w3fse,, you
happen incidentally to mention it to an
elder friend, who astonishess you, per-
haps, by saying: my dear fellow, You

course Of; Natsrs, and you must accept
the fiat. She now declares that she is NO
longer able of herself to do her work
properly, and that art must lend its aid.
And just here comes in very gener-
ally accepted error. It is currently be-
lieved that the use of glasses should be
put of IS long IS possible; that q too early
use of them is injurious, and that when
once begun, it becomes, earlier than it
should be, necessity. As the office of
the glass is to supply the refracting power
which the eye, through age, can no longer
furnish, il is evident that so soon as q
need Of this artificial power is felt we
should resort to it. By failing to do So
we deprive ourselves of much useful work
Of the organ, while the work it does is
done under disadvantage ind with
greater or less risk. S~izslggs

Inconvenience will first be felt in the
use of the eyes in the evening, and for a
year or more you may confine the use Of
your glasses to work at that time. But
soon they will become necessary during
the day, especially ii you have work re-

the light is not good.
Under ordinary circumstances, and
when the eyes are in other respects healthy,
the first glasses should be weak-say about
No. 60, according to the numbering in
this country. Such number, however,
should be selected as will enable you to
read the finest print at thirty centimeters
twelve inches). After the lapse of a year
or. two you will find it necessary to in
crease the number Of your glasses to about
forty-eight, and you will Ind that these
will serve both for evening and day work.
As regards the frequency with which the
glasses have TO be changed, it differs in
different individuals. AS general rule, 4
however, they should be increased as
much as the Individual case may demand
every five or seven years always keeping
The :" near point Of good, clear vision at
about twelve inches. The general health
will influence this largely, the weak,
nervous woman feeling the need of an in ]
crease in the strength Of her glasses much
sooner than robust, healthy man. Those
who use their eyes much, especially if at
trying work, will also experience de-
mand f0r . more frequent change.
These rules apply, as previously men
TONED, to eyes in a perfectly normal con-
elton. Shortsightedness and far-sightsd-
ness influence the necessity fer glasses to
j great degree. Short sighted persons can

may live to green old age without ever
having occasion to use them. On, the
other hane, far-sighted persons feel the
need Of assistance very early-often as
early - the 25th or ,30th year. ~
A few words now as to the glasses them
selves. In the first place, bear in mind
that pebble - glasses are Q hnmbng.
Even ii they are what they are repre-
lented>to be, and areinade OF pure crys-
81. they can serve NO hetter purpose than
Il made of good efear. glass. They are
harder than ordinary glass, and thus less
liable to be scratched, but that virtl1e,is
hardly an equivalent fer the ten or fifteen
dollars extra which the optician demands
Tor his superior spebbles,n which,
among other recommendations. are
!. warranted to strengthens tlid eyes by

class, free from defects and accurately
gr0und, which in q neat steel frame cost
about three doAarssor less; will do as
much g the pebbles; for which twenty
