I have a 13 year old son who has double vision. He has problems with distance and close up work. This has been going on for a year. He has an eye appointment in two weeks to be re-assessed. Consultant said we need to re-evaluate his convergence weakness. I am desperate for him to go to school. He had 140 days off school last year. He has only done two full days this term and the odd hour. I need to speak to the school about accomodating him, but not sure who this can be done. He can read the white board or read close up. Also can't find a prism to correct the problem. Any ideas out there.
