Hi Kriston,
I would definitively check your DS with a behavioral optometrist. He does not need to read to be checked.
I copy what I posted about DD in the other forum:
About the vision problems: we went to see an optometrist in Spain and indeed, DD has some deficiencies. She has problems tracking a fixing objects, not severe but enough to give her trouble, and she has problems with accommodation on short distances, which means that after a short while the page she is looking becomes all blurry. She has given me a few exercises to do at home and she told me that in about 4 months I should see improvement. Interestingly enough, DD's accuracy is 100% in the 'bad' eye and 120% in the 'good' one!
One of the things that indeed does not compute with DD is that she is not reading yet, despite the fact that she has lots of interest to learn and asks me to 'teach' her. My 'method' is reading to her while I point at the words as I read them, but she quickly gets tired and wants to stop after a few sentences.
So, if you gut feeling tells you that your DS should be reading, then trust four gut feeling more than anything else, including yourself!
