To reverse the effects of eyestrain, adapt your work environment to your body posture instead of adapting your body posture to your work environment. It should be four to eight inches lower than eye level. Position the monitor as if it were a book or magazine, so that the eyes look slightly down towards it. Large-screen monitors with a higher pixel count and higher refresh rate prevent eyestrain. Light sources should be perpendicular to the computer to avoid reflection on the screen or directly into the eyes.
Glare screens are also available to combat reflection problems.
Dust the screen with an anti-static cloth to keep fingerprints and smudges from making the image on the monitor look fuzzy. An eye exam from your ophthalmologist can rule out eye disease. Look for the cause of eyestrain in your surroundings. Recommendations on this web site do not endorse any commercial products or trade names.
