Ds 1 is rubbing his eyes when we he does anything close up. Not complained of not being able to see but pokes and rubs his eyes. Doesn't so this any other time. My brother wore glasses from 3 and I had trouble with my eyes not working together properly from school age -close up work highlighted the problem. Have made an app for ds 1 on fri -how will they test his eye sight as he doesn't know all of the alphabet? I know I'm being thick but I would think it possible surely?
