Best Frame Size for Computer Glasses: What I Discovered

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.

Why I Needed Computer Glasses

I work at a computer 8-10 hours daily. My regular glasses were causing:

• 
  
• Eye strain by end of day
• 
  
• Neck pain from tilting my head
• 
  
• Headaches in the afternoon
• 
  
• Difficulty focusing on the screen
• 
  

My optometrist recommended computer glasses with a specific prescription for screen distance.

My First Mistake

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.

The Ideal Size for Computer Glasses

Through research and consultation, I learned computer glasses need:

• 
  
• Larger lens width: 54-56mm (vs 52mm for my regular glasses)
• 
  
• Greater lens height: 38-42mm minimum
• 
  
• Wider field of view: To see entire screen without head movement
• 
  

Why Larger Frames Work Better

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.

The Height Factor

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.

What Other Computer Users Shared

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.

Frame Style Considerations

For computer glasses, I learned certain styles work better:

Best styles:

• 
  
• Rectangular frames with good height
• 
  
• Large square frames
• 
  
• Slightly wraparound designs
• 
  

Avoid:

• 
  
• Narrow rectangular frames
• 
  
• Small round frames
• 
  
• Rimless styles (less glare protection)
• 
  

My Current Computer Glasses Setup

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.

The Results

Since switching to properly sized computer glasses:

• 
  
• No more afternoon headaches
• 
  
• Reduced neck strain
• 
  
• Better focus throughout the day
• 
  
• Less eye fatigue
• 
  

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.
