Before we establish if and how broken eyeglasses can be fixed on Shabbos,
let us list the halachic violations that may be incurred when doing so.(1)
Our discussion covers the two most common mishaps - a temple (earpiece)
breaking off from a frame, and a lens popping out of a frame. There are
three areas of concern:
On Yom Tov(.12)
As mentioned above, the Shulchan Aruch uses a stove as his case in
point. The Rama adds that the same rules apply to a bench whose legs
became detached. Most latter-day poskim(13 )agree that all similar objects
are included in this Rabbinic prohibition.(14 )It follows, therefore, that
the halachos concerning a temple which becomes detached from its frame
will be similar to the cases of the stove and the bench mentioned above.
BASED ON THESE PRINCIPLES, WE CAN NOW ANSWER THE FOLLOWING
Q: Can the temple be screwed back onto the frame?
A: Strictly forbidden, according to all views.
Q: Can the screw be inserted into the hinge without tightening it?
A: No. The prohibition of shema yitka applies. On Yom Tov, however,
Q: May one wear the glasses while only one temple is attached?
A:On Yom Tov, yes.
On Shabbos, however, it depends: If the detached temple or screw is lost,
it is permitted to wear the frames minus the temple, since gezeiras kirah
does not apply. If the detached temple and screw are accessible, the
frames become muktzeh. If, however, it is acceptable to be seen in glasses
that have a missing temple, the glasses may be worn.(15 )If it would be
embarrassing to be seen in such glasses, gezeiras kirah applies and the
frames are muktzeh.(16)
If the temple broke off before Shabbos and the glasses were already
worn in their broken state, all poskim agree that it is permitted to wear
them on Shabbos, regardless of whether the other temple or screw is
missing or not.(17)
Q: Can the temple be attached to the frames using a wire or a pin?
A: If the original screw, or a replacement, is available, then the
temple, and screw are muktzeh, based on gezeiras kirah. Consequently, they
may not be moved at all on Shabbos.
If the screw is lost and no replacement is available, then gezeiras
kirah does not apply. It is permitted to attach the temple to the frames
using a safety pin, provided that it will be removed after Shabbos.(18)
[The poskim, however, do not permit attaching the temple to the frames
using a wire or a needle, even if the wire or needle is not firmly
tightened around the frame.(19])
On Yom Tov, since shema yitka and gezeiras kirah do not apply, it
would be permitted to attach the temple using a pin or wire [as stated
above], regardless of whether or not the screw is lost.
Q: There are frames (usually plastic ones) that hold the lens in
merely by exerting pressure on the lens; there is no screw involved. What
can be done if a lens pops out of such frames?
A: If the lens pops out because the pressure on it has slackened
the frame expanded slightly due to wear and tear), then it may be
reinserted.(20)If, however, the lens is knocked out forcibly and would
have to be forced back in, then the poskim differ in their opinions. Some
are stringent and forbid re-inserting it on the grounds of tikun keli(,21)
while others do not consider this an instance of tikun keli since the lens
can be re-inserted with minimal pressure.(22 )
Q: What can be done if the frames break in half?
A: Nothing. Since they can no longer be worn, the frames are severe
muktzeh and may not be moved for any reason.

loosely inserting the screw without tightening it. In his opinion, shema
yitka only applies when the pieces are tightly fitted together.

cases specifically mentioned in the original sources: a stove and a bench.
This is the opinion of Imrei Yosher 1:102, Chelek Levi O.C. 101, and Beis

According to this opinion, the frames and the lenses would now be muktzeh,
due to gezeiras kirah.
