Color Blind Glasses: What They Do, Who They Help, and What to Expect

Color blind glasses use tinted filters to shift how reds and greens look to people with red-green color blindness (color vision deficiency). They do not cure color blindness, and peer-reviewed studies show results that vary by person, deficiency type, and the test being used.⁵⁷

If you are weighing a purchase, the honest answer is that some people with mild red-green deficiency notice real differences in everyday color tasks, while others see little change on standard clinical tests.²⁸ This guide walks through how the glasses work, who tends to benefit, what the research shows, and what current prices look like.

How Color Blind Glasses Work

Color blind glasses are tinted lenses that filter out specific wavelengths of light, mostly in the 530 to 560 nm band where the red and green cone responses overlap most.¹² Cutting that overlap is meant to increase the contrast between red and green signals, so colors that normally look similar become easier to tell apart.

A few details matter for how the glasses behave in practice:

• Selective wavelength filtering: The lenses block narrow bands of light rather than darkening the scene evenly, which is what separates them from sunglasses.¹⁴
• Contrast enhancement, not correction: The glasses do not repair the underlying cone cells. They change the light that reaches your eye so existing cones receive a clearer signal.⁷
• Indoor and outdoor lenses: Outdoor lenses are darker and tuned for bright sunlight. Indoor lenses are lighter and meant for screens and artificial lighting. Most brands sell both, and the right pick depends on where you plan to wear them.¹⁴

Who They Help (and Who They Don't)

Color blind glasses are most plausibly useful for anomalous trichromacy, the milder form of red-green color blindness. They are less useful for stronger dichromatic deficiencies and not designed for blue-yellow or complete color blindness.⁷¹⁴

• Protanomaly and deuteranomaly (mild red-green): The best candidates. Studies show measurable changes in how these wearers perceive red-green stimuli, though improvement does not show up on every clinical test.¹⁴
• Protanopia and deuteranopia (strong red-green): Some benefit is possible, but effects are smaller and less consistent than in anomalous trichromacy.³⁹
• Tritan-type (blue-yellow) deficiency: Limited and uncertain benefit. EnChroma and similar brands target red-green wavelengths, not blue-yellow.⁷¹⁴
• Monochromacy (complete color blindness): Not a good fit. The deficiency involves missing cone function the glasses cannot work around.⁷

Before buying, it helps to know your specific type of color blindness. An eye care provider can run a standard Ishihara test, plus more detailed assessments like the Farnsworth D-15 if needed. EnChroma and Pilestone also publish online color vision tests on their sites for a rough screen.¹⁴

What the Research Says

Peer-reviewed evidence on color blind glasses is mixed. Several studies show changes in color appearance and some discrimination tasks, but no high-quality study supports the claim that the glasses restore typical color vision.⁵

A few findings worth knowing:

• Somers 2024 (EnChroma, deuteranomaly): Found significant effects on some color-matching and appearance measures, but only small effects on threshold discrimination. Improvement was task-dependent.¹
• Bastien 2020 (EnChroma): Reported small benefits on certain stimuli and undesirable effects on others. The authors concluded the glasses did not correct color discrimination.²
• Gómez-Robledo 2018 (EnChroma): Did not find a significant improvement across all test conditions.³
• Pattie 2022 and Mouffokes 2025 (EnChroma): Both reported no overall improvement on standard clinical color-vision tests.⁸⁹
• Male 2022 systematic review: Pooled the existing evidence and concluded it is insufficient to show clinically meaningful improvement in subjective color perception.⁵
• Patterson 2022 (EnChroma and VINO): Both brands showed statistically significant CAD-test effects, with VINO described as more functionally meaningful in that test context. The authors stopped short of saying either brand corrects color blindness.¹²

The pattern across studies is consistent: the glasses can change how colors appear, sometimes in ways wearers find useful, but they do not restore normal color vision and they fail many standard clinical tests of color discrimination.⁵

Brands Compared

Several brands sell color blind glasses with different price points, lens approaches, and return policies.

Choosing Indoor or Outdoor Lenses

Outdoor lenses are darker and tuned for sunlight. They are the most common starting point because the red-green contrast effect is easier to notice in bright daylight, where reds, greens, foliage, flowers, clothing, and other everyday outdoor colors are common places wearers notice differences.¹⁴

Indoor lenses are lighter and designed for screens, school, and office settings. If most of your color tasks happen at a computer or under artificial light, indoor lenses are usually the better pick. Some brands sell prescription pairs in both formats so you can switch by setting.¹⁴

What Color Blind Glasses Cost

Color blind glasses cost about $100 to $400 for most consumer brands.¹³ Pilestone sits at the lower end ($80 to $150), EnChroma and VINO Optics in the middle ($200 to $400), and the custom ColorCorrection System runs $3,000 to $10,000 or more.¹⁵ Children's frames usually start around $189.

Prescription lenses typically add $100 to $150 on top of the base price. Insurance coverage and FSA or HSA eligibility vary by plan, since most insurers consider color-correcting lenses non-medical. Check with your insurer or FSA/HSA administrator before assuming the glasses will be reimbursed.

Some brands run periodic discounts and EnChroma offers a 60-day money-back guarantee, which is the safest way to test whether the glasses do anything noticeable for you before committing the full cost.¹⁴

Are They Worth It?

Whether color blind glasses are worth the cost depends on your deficiency type, what you want them to do, and how comfortable you are with mixed evidence. The honest framing is that some wearers report a real difference in everyday color tasks, while controlled studies do not show consistent improvement on clinical tests.⁵

A few factors that should shape the decision:

• Realistic expectations: Viral "first time seeing color" videos are anecdotal. Peer-reviewed evidence shows variable results across people and tasks.¹⁵
• Not for driving or low-light vision: Filtered lenses block light, which dims your view and can slow reaction time in low light. Do not wear them while driving, day or night.¹³
• Other eye conditions: Filters may be less helpful for people with cataracts or macular degeneration, who often need extra brightness rather than less.
• Safety-critical tasks: Do not rely on color blind glasses for any color decision where safety is on the line. That includes driving, aviation, electrical or live-wiring work, and medical settings, where the benefit is too variable to substitute for proper accommodations or alternative cues.¹⁰¹³
• Not a substitute for accommodations: Students with color vision deficiency may need classroom accommodations regardless of whether they wear filters. Glasses may help with some color-coded tasks but should not replace formal support.⁷
• Not the same as contrast-enhancing glasses: Hunting and photography filters boost contrast but are not designed for color blindness.

Practical Benefits Some Wearers Report

For the right candidate (anomalous trichromacy, willing to accept mixed evidence), color blind glasses can change how some common color tasks feel.⁵⁶

• Color-coded study and office tasks: Charts, graphs, classroom materials, and other non-safety-critical color-coded items may become easier to distinguish. The glasses are not a sufficient aid for live wiring, electrical work, or other tasks where a wrong color call has safety consequences.
• Art and visual experience: Some wearers report a richer experience with paintings, photography, and natural scenes outdoors.
• Daily life: Picking ripe fruit, matching clothing, and reading red-green color cues on screens often becomes less of a guessing game for milder deficiencies.

These benefits are real for some wearers and absent for others. A return-policy trial is the most reliable way to find out which group you are in.¹⁴

Where to Buy

Color blind glasses are sold directly through brand websites, including EnChroma, Pilestone, VINO Optics, and ColorMax. Buying direct usually gives you the clearest return-policy coverage and access to the brand's online color vision screening test.

You can also find EnChroma and several other brands on Amazon, but availability, pricing, and lens options vary. The brand sites are typically the safer bet for prescription orders, indoor-versus-outdoor lens selection, and warranty support.

Find an Eye Doctor

An eye care provider can confirm your color vision deficiency type, walk through whether tinted lenses are likely to help in your case, and discuss alternatives like color-identification apps and workplace accommodations. If your color vision has changed recently, only affects one eye, or seems to be getting worse, book an exam instead of buying glasses. Color vision changes that come on later in life can point to eye disease, cataracts, neurologic problems, or a side effect from medication, and those need a workup rather than a tinted lens.⁷
