EnChroma Cx3 Outdoor
EnChroma is the brand most people have heard of, and the Cx3 Outdoor is their best lens for sunny conditions. The first time I wore them on a hike in autumn, the reds in the foliage jumped out so clearly I stopped walking. They are not magic for every person, but for moderate deuteranopia or protanopia, the difference is real and immediate.
As a deuteranope, I have tested every major colorblind glasses brand on hikes, screens, and traffic lights. These five actually do something.
I have moderate red-green color deficiency, which I confirmed with both Ishihara plates and an anomaloscope test. I have tested colorblind glasses for almost a decade, and the field has matured a lot. The good news: for red-green deficiencies the lenses really do something. The honest news: results vary by person, and outdoor-bright conditions produce the strongest effect. Here are the five pairs I keep recommending.
| Glasses | Lens Type | Use Case | Best For |
| — | — | — | — |
| EnChroma Cx3 Outdoor | Tinted polycarbonate | Outdoor sun | Strongest outdoor effect |
| Pilestone TP-029 | Mineral glass | Outdoor and driving | Best value |
| EnChroma Indoor | Light tint | Screens and art | Office and indoor use |
| Covisn TPG-038 | Polycarbonate | All-around | Versatile budget |
| Pilestone TP-025 Sport | Wraparound | Active sports | Cycling and hiking |

EnChroma Cx3 Outdoor
EnChroma is the brand most people have heard of, and the Cx3 Outdoor is their best lens for sunny conditions. The first time I wore them on a hike in autumn, the reds in the foliage jumped out so clearly I stopped walking. They are not magic for every person, but for moderate deuteranopia or protanopia, the difference is real and immediate.
Pilestone TP-029
Pilestone makes the value pick I most often recommend. The TP-029 lens does similar wavelength filtering as EnChroma at roughly a third of the price. The frames feel a step less premium, but the optical effect is comparable. Mineral glass lenses are heavier than polycarbonate but stay scratch-free longer.
EnChroma Indoor
Indoor lenses are far lighter in tint, designed for screen work and indoor lighting. The effect is subtler, but for office workers who need to interpret color-coded charts, dashboards, or design files, they are a real productivity tool. I wear mine when I review code with red error highlighting.
Covisn TPG-038
The Covisn TPG is the most versatile budget option. The lens tint is moderate, which makes them usable both indoors and outdoors. Frames are plastic and feel cheap, but the lens performs better than the price suggests. A good first pair if you are not sure colorblind glasses will work for your specific deficiency.
Pilestone TP-025 Sport
For active use, a wraparound sport frame is non-negotiable. The TP-025 Sport gives the same lens treatment as Pilestone's regular outdoor lenses in a frame that does not bounce off your face when you run. Lens venting prevents fogging on climbs. I wear these for mountain biking specifically.
Quick answers
For the most common red-green deficiencies, yes, but the effect varies by person and by lens design. The glasses work by notching out wavelengths of light where red and green overlap, which sharpens the contrast between those colors. They are not a cure, but the effect on foliage, sunsets, and traffic lights is genuine.
Outdoor lenses are tinted darker and shine on bright sunlit foliage and outdoor sports. Indoor lenses are lighter and made for screens, art, and office lighting. If you can only have one pair, get outdoor lenses for sunny days and use them as sunglasses.
