What it is
Color blindness, more accurately called color vision deficiency, means the eyes' color-sensing cells work differently than most people's. It is often inherited and is more common in men, though it can also be linked to certain eye conditions, health issues or medications. Many people have it for life without realizing it.
There are several types. Protan and deutan types affect how reds and greens are seen, while tritan types affect blues and yellows. Each type can range from mild to more significant, and two people with the same label may see the world quite differently.
Color blind glasses, often called color-enhancing or color-filtering glasses, use specially tinted lenses that change how certain wavelengths of light reach the eye. They may make some colors appear more distinct for some people in some settings. They do not repair the eye's color-sensing cells, they do not cure color blindness, and they do not give normal color vision.
How it’s traditionally been approached
Traditionally, most people with color vision deficiency have adapted through everyday strategies, such as learning to rely on brightness, labels, position (like the order of traffic lights) and help from friends, family or coworkers. Many simply find ways to work around color-dependent tasks.
Color vision has usually been checked with screening plates or arrangement tests, and more detailed testing can help identify the type and severity. Knowing whether someone is protan, deutan or tritan, and how pronounced it is, has long been the starting point for any conversation about options.
Color-enhancing glasses and contact lenses are a more recent option that some people explore. Results are mixed and personal: some people find them useful for certain situations, while others notice little difference. Effectiveness depends on the specific type and severity, and tritan types in particular are often treated differently from red-green types, so it's worth asking a professional about your own situation.
How the right doctor may help
A comprehensive color vision test with an eye care professional is often the clearest way to learn your type and severity. A visit generally includes a history of your vision and family background, one or more color vision tests, and a conversation about which color tasks matter most in your daily life or work.
If you're considering color-enhancing glasses, a provider experienced with them may help you understand whether your type is one where they are commonly tried, what they may and may not do, and how to try them in realistic settings. Only a licensed clinician can decide what is appropriate for you after an evaluation, and these glasses are not a medical treatment or cure.
Helpful questions to ask: What type and severity do my results show? Is there a reason to believe glasses might help my type? What should I realistically expect? Can I try them before committing? Do the glasses affect safety-related tasks like driving or work duties? Is there any trial or return policy? Also ask about the regulatory status of any product you're considering, since consumer color-enhancing eyewear is not the same as a medical device prescribed to correct a condition.
The whole-person view
Seeing color differently can affect more than vision. Frustration at school or work, worry about safety tasks, or self-consciousness in social settings can build up as stress, and stress can in turn show up in the body through tension, poor sleep or fatigue. Body, mind and daily stress all influence each other, so caring for the whole person can matter alongside any eye-related question.
If the emotional side of living with color blindness feels heavy, some people find body-based support through Somatic Experiences helpful for working with stress held in the body. Others prefer talk therapy, and Therapists.plus can help you find a therapist to talk things through. Neither is a substitute for an eye exam, and every approach has its place.
Keep in mind
- This page is educational only and is not medical advice; a licensed eye care professional should guide any decisions about your vision.
- Color-enhancing glasses do not cure color blindness or restore normal color vision, and results vary by type (protan, deutan or tritan) and severity.
- Career and licensing color vision standards, such as aviation, military, law enforcement, commercial driving, electrical trades and maritime work, vary and change over time, so confirm current requirements with the specific employer, licensing body or agency, and don't assume glasses will meet them.
- If you notice sudden changes in your vision, call a licensed provider promptly; for emergencies call 911, and in a crisis call or text 988.
Doctors who often help
Get matched privatelyFrequently asked questions
Do color blind glasses really work?
Color blind glasses may help some people see certain colors as more distinct, but they do not cure color blindness or restore normal color vision. How well they work varies by your specific type and severity. A licensed eye care professional can help you set realistic expectations.
Will color blind glasses work for my type of color blindness?
It depends on whether your type is protan, deutan or tritan and how significant it is. Red-green types are the ones most commonly discussed with color-enhancing glasses, and results still differ between individuals. Comprehensive color vision testing is the best way to learn your type before buying.
How do I find out which type of color blindness I have?
A color vision test with an eye care professional can identify your type and severity. Online screenings may hint at a difficulty, but they are not a diagnosis. A professional can use more detailed tests and explain what your results mean.
Can color blind glasses cure color blindness?
No, color blind glasses cannot cure color blindness. They filter light in ways that may change how some colors look, but the underlying way your eyes sense color stays the same. Be cautious of any product that claims to fix or cure it.
Are color blind glasses FDA approved?
Regulatory status can vary by product, and many consumer color-enhancing glasses are marketed as general-use eyewear rather than as prescribed medical treatments. Ask your provider and check the product's own materials to understand how a specific item is classified. Don't assume that being sold means it's cleared for medical use.
Can I wear color blind glasses for work that requires color vision?
Not necessarily. Color vision requirements for jobs like aviation, military service, law enforcement, commercial driving, electrical trades and maritime work vary by employer and authority and change over time. Confirm current rules, including whether any aids are permitted, directly with the employer, licensing body or agency.
