i seem to spend all day cleaning the LOL! we have been back to shop twice so far and i have to go again when i go to town, 1st was cos they slipped off, 2nd the lense fell out and now hes lost the rubber bit that goes on side of nose.
luckly we got 2 pairs when we got them. he has got much better and he puts them on when he gets p etc and keeps them on for most of day.
