Do Color Blind Glasses Work?

By The Detect Color Blindness editorial team Last reviewed
Colour-blind glasses can boost the contrast between reds and greens for some people with mild-to-moderate red-green deficiency. They do not add missing cones, do not 'cure' colour blindness, and generally do not help blue-yellow (tritan) or total colour blindness. Results are personal, look for a genuine return window and try before you commit.

Which is best for your type?

EnChroma

The best-known brand. Works only for red-green (anomalous trichromacy) and does not restore missing cones, it increases separation between reds and greens for some users.

Pilestone

A lower-cost alternative with multiple tint options for different severities. Effect varies by individual and lighting.

ColorLite

Filters are specified per person after an online or in-clinic assessment, and can be made to prescription.

Before you buy

  • Know your type first. Glasses target red-green deficiency. If your test result is blue-yellow or total colour blindness, they're unlikely to help.
  • Mild beats strong. Anomalous trichromacy (mild) responds better than dichromacy (strong).
  • Try before you commit. Effect is personal, insist on a real return window.
  • They're not a pass. Most official colour-vision requirements (aviation, driving, some jobs) are assessed without glasses.

Frequently asked questions

Do color blind glasses actually work?
For some people with mild-to-moderate red-green deficiency they increase the contrast between reds and greens, which can make certain colours 'pop'. They don't add missing cones, don't cure colour blindness, and generally don't help blue-yellow or total colour blindness.
Will glasses make me pass a color vision test?
Usually not, and many official tests (aviation, driving, some jobs) are taken without them. Glasses change how colours look through the lens; they don't restore normal cone function.
Which color blind glasses are best?
It depends on your type and severity, indoor vs outdoor use, and budget. Compare EnChroma, Pilestone and ColorLite, and choose a brand with a genuine return window so you can try them first.
