My grand-daughter has just had glasses and cannot keep them on her nose. There is a strap which would go round the back of her head which would do the job but as to where I would get one of these or the correct name for them. Any help would be appreciated
if she has a very dainty little nose she may need the side pads changing also the bit that goes round the ears can be extended to curve further round I had the same problem when I was younger. Superlight plastic lenses help too they don't come free unlike the standard kiddy ones but make a huge difference
as said your optician should have made these fit correctly to start with.
one tip though is she uses a face moisturiser keep it off the top of the nose where the glasses pads rest on. it makes the glasses slide off because of the oil in the moisturiser
