both my dc's have glasses, dd has pretty poor eyesight, she's a +5 in one eye and a +6 in the other, and has a squint in the weaker (left) eye. she's had glasses since she was 18 months. this was in 2003, and then, they did used to make the prescription out for 2 pairs, knowing full well that children of that age always bend and break them. we always had one pair at home and the other pair at the opticians being repaired. but when ds got his prescription, i mentioned about the 2 pairs and was told they don't do that anymore on the nhs, basically, if you want a second pair, you have to pay for them.
when dd needed a larger frame, she only got 1 pair, and basically she can't see a thing without them, if they broke, she'd be totally stuck at school unable to see, so i'm afraid i lied, we went back a few weeks later and i just said she'd lost them at school after pe , we did get another pair. i know it was wrong to do that, but at least she has a spare pair now.
we are also having to do patching with dd, 2 hours a day to exercise the lazy eye. dd broke them loads when she was little but soon realised she needs to wear them, she has double vision without
dd has never been teased about them, in fact, most of her class mates think wearing glasses is pretty cool, and keep asking why they can't have some
ps, if you ever need to do any patching, dd hated the patches the optician gave us so i made her a pink one with a flower on it out of felt, it slips on over her glasses and she finds it much more comfortable to wear, let me know and i'll make one for your dd
