I have donated 12 pairs of eyeglasses to their collection point which is in Al Attar Gold Building in Al Mina Road in Bur Dubai.
The eyeglasses are sent to Al Shifa Trust Eye Hospital, Rawalpinid, Pakistan and are donated to the poor.
I think that during Ramadan the Outlet mall do a collection and they accept glasses, not sure about anyone else, Red crescent can be extremely picky about what they will accept, maybe hang on to them until Ramadan and drop them in to the collection point at Outlet Mall.
