When he was asked to read a bit he screwed up his face and asked the guy if he could make it bigger!!!!
He was then asked if he could see better with the first lense or the second " I can't see anything silly" he replied.
The guy decided he is longsighted and worse in his left eye, whcih would explain the sore heads so he recommended glasses for a few months initally.
We went to look and the glasses and we were there FOREVER. he tried loads on and we got it down to 3 pairs and he must have had them on about 4 times each. We have finally settled on a pair and they should be ready beginning of the week. Now just got to persuade him that he ahs to wear them all the time at shcool
