He's been checked at the hospital re his eyesight, because he is very longsighted, and has a squint, and lazy eye. It's all going against him, poor lad.
They have confirmed that with his current glasses he can see all letters both in distance (i.e. reading board) and close up. But has trouble with convergence, of identifying the middle letters, not the ones at the end. This is where the blue overlay helps, as it keeps the letters separated.
He is not suitable for having the tint on his lenses, as he would need to have green for distance reading, blue for close up reading and clear to function in everyday. They advised it was too much for a 5 yr old to have 3 pairs of glasses, and to keep changing them, whilst looking up, down and going out to play.
They tested with the pictures rather than words.
The reason for the testing, is that according to school his mathematics supposedly is far ahead of his age, whilst is english is just below where it should be. I am severly dyspraxic, and my dd is severly dyslexic but had come up with her own coping techniques which meant although there was concern about the difference between English and Maths subjects, she wasn't seen as having a problem. Now entering her GCSE year, she still can't read/write, and everything is phonetic, but because she's learnt the key words (i.e. the picture they look like rather than reading them) she has worked out what questions want. I was concerned that her brother had the same problem, and unfortunately it appears he does.
