Q. A talmid chacham who has a minhag to remove his spectacles from his face whenever he goes outside to avoid seeing forbidden sights – what should he do when he walks in the reshus harabbim on Shabbos? Should he be concerned that he may inadvertently remove his spectacles due to his weekday habit? If so, what should he do?
A. Horav Shlomo Miller’s Shlit’a opinion is that, he may secure his glasses on Shabbos with a customary strap or chain, so he will remember not to remove them.
Rabbi A. Bartfeld as advised by Horav Shlomo Miller Shlit’a
