– Q. My wife went to the eye doctor because she was having vision problems. The doctor gave her a new prescription for her lenses and she ordered a set of new frames and lenses. For various reasons she couldn’t pick up the new pair of glasses until today, Erev Shabbos Chazon. Is it acceptable for my wife to get the glasses and wear them before or on Tisha B’Av?
b) Could she also wear them even if they were unusually beautifully decorated and elegant?
c) How about similar needed sun glasses?
A. Yes, it is all permitted.

D) See question above:
Can women wear jewelry on Tisha B’Av.?

A.
Poskim maintain that if possible it should be avoided, also some
Poskim opine, during
all the nine
days. (Eishel Avrohom (Butatch), Piskei Teshuvos (551).)
