Computer vision
« Reply #1 on: July 15, 2011, 11:49:43 AM »
Q: My eyes are 52 years old and I am interested in preserving my vision as long as possible.  Could you give me your recommendation for the specs for a computer screen that would be suitable for work where I spend at least 4 hours a day looking at the screen.  Parameters would include refresh rate, pixel density, dot pitch, and screen size.  I would like to make a pitch to my employer to upgrade my monitor.
A: These are two independent questions, because the monitor in use is unrelated to the eventual health of one's eyes. Typically people over 45 are presbyopic and require extra glasses power to see near objects. If the near object is large enough,though,glasses may be unnecessary. From this standpoint, the larger the monitor, the better. For visual comfort (not health) a refresh rate over 75 and pixel size of less than .27 and dpi of 72 seem to be commonly recommended. Good luck with the boss.
