One problem that could be causing this is the eye's being out of alignment in the vertical direction. If the eyes are the least bit out of alignment vertically, straining to see or double vision could occur. This finding is often not measured during the course of an examination.
Also, when an individual has a very significant difference in prescription between the two eyes, especially with bifocal wearers, the patient can feel this same strain. Regarding this particular situation, prism might need to be added to the prescription to help compensate for this difference between the two eyes.
