After years of eye strain from computer work, I got dedicated computer glasses. But I learned that the best frame size for computer glasses is different from regular glasses, and choosing the wrong size made my eye strain worse.
I work at a computer 8-10 hours daily. My regular glasses were causing:
My optometrist recommended computer glasses with a specific prescription for screen distance.
I used the same frame size as my regular glasses: 52-18-140. This was wrong for computer use.
Computer screens are at a specific distance (20-26 inches), and frame size affects your viewing angle and comfort at that distance.
Through research and consultation, I learned computer glasses need:
Computer glasses benefit from larger frames because:
Wider peripheral vision: I can see my entire monitor without turning my head.
Better coverage: Larger lenses block more ambient light and reduce glare.
Reduced eye movement: My eyes don't have to work as hard to scan the screen.
More comfortable viewing angle: I can maintain better posture without tilting my head.
Lens height is crucial for computer glasses. I need at least 40mm vertical height to comfortably view my screen without constantly adjusting my head position.
My regular glasses have 35mm height, which is fine for general use but too short for extended computer work.
Reading forums about computer glasses, I found common themes:
One programmer shared that switching to larger frames for computer work eliminated their chronic neck pain.
Another person mentioned that they use 54mm frames for computer glasses but 50mm for regular glasses.
Someone else noted that wraparound styles help block side glare from windows.
For computer glasses, I learned certain styles work better:
Best styles:
Avoid:
I now use 54-18-140 frames for computer work, compared to 52-18-140 for regular use. This 2mm difference in lens width provides significantly better screen coverage.
The larger frames also accommodate blue light filtering lenses better, giving me more protection from screen glare.
Since switching to properly sized computer glasses:
If you work at a computer extensively, consider dedicated computer glasses in a slightly larger frame size than your regular glasses. The difference in comfort is remarkable.
