My brother has red-green color blindness, and watching him experience colors he had never seen properly was one of the most striking things I have done as a writer. We compared several brands together and the results varied widely. Here are the five that delivered for him.
| Glasses | Type | Best For |
|---|---|---|
| EnChroma Cx3 Outdoor | Spectral filter | Outdoor red-green CVD |
| Pilestone TP-018 | Outdoor budget | Affordable outdoor pick |
| EnChroma Indoor | Indoor filter | Office and home use |
| ColorMax | Custom prescription | Custom needs |
| Vino Optics O2Amp | Specialty | Specific applications |
EnChroma Cx3 Outdoor
The EnChroma Cx3 is the brand that started the modern colorblindness glasses category, and for good reason. My brother put them on outside on a sunny day and stopped mid-sentence to stare at a flower bed. Outdoor performance is excellent for red-green CVD. The frame designs are styled like real sunglasses.
Pilestone TP-018
Pilestone is the budget alternative that costs a fraction of EnChroma. For my brother, the effect was a bit less pronounced but still very real. If you are not sure colorblindness glasses will work for you, starting with Pilestone is a sensible test before spending more.
EnChroma Indoor
The Indoor version is tuned for office and home lighting where the standard outdoor glasses are too dark. My brother uses these at work to better differentiate color-coded charts and screens. The effect is more subtle but useful in artificial light.
ColorMax
ColorMax offers custom prescription lenses that combine vision correction with colorblindness filtering. For people who already wear glasses, this is the option that avoids stacking lenses or switching to contacts plus over-glasses. Order through an optometrist.
Vino Optics O2Amp
Vino Optics makes specialty filters designed for specific applications like medical color recognition. They are not a general-purpose colorblindness fix, but for niche professional use cases they offer something the broader brands do not.
What Matters Most
The type of color blindness matters most. These glasses primarily help red-green CVD, the most common form. They do not help blue-yellow or total color blindness. After that, consider whether you need outdoor or indoor versions, or both.
My Setup
My brother now keeps two pairs, an outdoor EnChroma Cx3 for daily use and an indoor pair for work. He still has color blindness but in good light conditions he sees differences he could never see before. The glasses do not cure CVD but they meaningfully expand his color world.
Common Mistakes
The biggest mistake is expecting a cure. These glasses enhance color contrast but do not change how your eyes process color. The second mistake is buying outdoor glasses for indoor use, where the filter is too dark for normal lighting.
Final Recommendation
For the strongest documented effect, the EnChroma Cx3 Outdoor is the proven pick. For a budget test, try Pilestone TP-018. For indoor work, the EnChroma Indoor solves a real problem, and ColorMax serves prescription needs.
Frequently asked questions
Do colorblindness glasses actually work?+
For most people with red-green color blindness, yes, they enhance color differentiation but do not cure the condition. Effectiveness varies by individual and type of color blindness.
Will they work indoors or only outside?+
Most spectral filter glasses work best in bright sunlight. Indoor versions exist but the effect is more subtle under artificial lighting compared to outdoor performance.
