[[Blur]] from uncorrected vision causes eye strain. This problem is solved by wearing the [[differential]] or [[normalized]] lenses that are most appropriate for the situation. Good ambient lighting will also go a long way to help avoid eye strain. More light means better vision, and natural light is the best light. | [[Blur]] from uncorrected vision, or severely under corrected vision, causes eye strain.
