So, you must have 20-20 vision, right?
Here are some simple measures to reduce and prevent eyestrain:
overhead strip or neon lighting reflecting in your computer screen
lighting of any kind directly pointing at you or in your immediate field-of-vision
metallic or other reflecting objects in the immediate surrounding area
an anti-glare sheet filter onto computer screen
letters/type so that text is clearly visible from 80 to 90 cm or so from screen to reduce the need for squinting
- Do not
position the screen against a bright background such as a window or other light source (*1 Your eyes will automatically try to compensate for 2 or more different light sources at the same time)
moving objects such as fellow workers behing the screen (see *1)
light or bright surfaces behind the screen (see *1)
matte green or other neutral color such as grey (ground concrete is excellent) or medium brown cardboard behind the screen
glasses at all times
(even LCD screens attract and reflect small particles of dust which strike and damage the retina)
eyedrops close by at all times
Except for "Fit an anti-glare sheet filter onto computer screen" I already do all that!
