We have just found out ds1 (8) is shortsighted and needs glasses Trouble is, he will need them for distance stuff, blackboard, TV, cinema, etc, but not all the time. He has Aspergers, and struggles with schoolbag, homework, PE kit, scooter, lunch box etc at the best of times, and I imagine that the glasses will usually be at school when he is at home and vice versa. So, 2 pairs would seem to be a good idea. BUT, the NHS voucher thing will only cover one pair of lenses, and the frames he wants are over £80 at our opticians, so where should I go to get a cheap spare pair to keep at school? Has anyone else done this?
