An ophthalmologist exam often/usually misses the complex issues of convergence insufficiency and a myriad of other problems of the eyes working together properly. The brain needs to work extra hard stitching each eye's image into a single image when the eyes are not working together properly.

It may be worth calling the ophthalmologists office and ask if they have a referral to a behavior optometrist.
