Is there any authoritative data that correlates screen size with eye-strain? There seems to be three opinions out there: 1. Screen size (with respect to physical dimensions) has no effect whatsoever on the amount of eye strain. 2. Some suggest a bigger monitor size can enable you to place it farther away(for the same visibility) which reduces eye strain. 3. And finally some say bigger the monitor size greater will be the radiations emitted that could potentially harm your eyes. Your thoughts?
