So, you must have 20-20 vision, right?
Here are some simple measures to reduce and prevent eyestrain:
-
No overhead strip or neon lighting reflecting in your computer screen
-
No lighting of any kind directly pointing at you or in your immediate field-of-vision
-
Remove metallic or other reflecting objects in the immediate surrounding area
-
Fit an anti-glare sheet filter onto computer screen
-
Enlarge 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)
-
No moving objects such as fellow workers behing the screen (see *1)
-
No light or bright surfaces behind the screen (see *1)
-
Place matte green or other neutral color such as grey (ground concrete is excellent) or medium brown cardboard behind the screen
-
Wear glasses at
all times (even LCD screens attract and reflect small particles of dust which strike and damage the retina)
-
Keep eyedrops close by at all times
Except for "Fit an anti-glare sheet filter onto computer screen" I already do all that!
