like LS i've had glasses since i was months old. long sighted, astigmatisms - and optic nerve that points the wrong way (should look like a donut facing forward to front of eye - mine lays flat). by the time i hit school, i was so used to having glasses that i apparently come home from school the first time i was called four eyes and asked my mum what it meant! the teasing is nothing unless your child has self esteem issues, which you can help with at home from the outset.

don't let your own perception of how hard it will be for your child cloud your judgement. the headaches from crappy eyes are horrific and debilitating - and catching problems early means they can be treated and even potentially corrected. from a teasing standpoint, it's more likely if you leave things til later - DH has a great niece whose parents put their own thoughts on glasses over the recommendations of specialists. his niece didn't get glasses until she was in about grade 4 when things had gotten quite bad with the turn in her eye. she was supposed to wear them for reading only, to help strengthen her eye, and wear a patch for some time everyday - she didn't want to "look like a dork" so she didn't do it. she had to have surgery on her eyes this year for something that could have baan corrected at a young age

my DD is 13weeks old and has a turn in her eye and will go cross eyed looking at objects up close to her, so will be getting referred to an opthamologist in a few weeks. family history makes the GP more wary of leaving it unchecked. if she has to have glasses, i won't be surprised at all (both DH and I wear them all the time) - it's better to get them younger and get used to it, then to leave it to a point where your child's vanity wins out
