Eyes & Vision
Color Blindness
A reduced ability to distinguish certain colors — most commonly red and green — usually inherited but sometimes caused by eye diseases, drugs, or nutritional deficiencies.
Also known as: Color vision deficiency, Red-green color blindness, Dyschromatopsia
📝 At a glance
Likely root causes: Inherited — most common form; faulty cone cells passed down genetically; Red-green color blindness is X-linked: passed from grandfather through daughters to grandsons; Macular degeneration and other eye disorders affecting the cones.
First thing to try: If inherited color blindness, understand that correction is not currently possible — adaptive strategies (labeling, apps, specific lighting) help with daily life.
See a doctor if: See a doctor if symptoms are severe, persistent, or worsening, or if you are unsure — natural supports are meant to complement, not replace, professional care.
🔎 Start with the cause
Lasting relief rarely comes from covering a symptom. First find what is feeding the problem, change what you can, and then help the body do what it was designed to do — heal.
Likely root causes
- Inherited — most common form; faulty cone cells passed down genetically
- Red-green color blindness is X-linked: passed from grandfather through daughters to grandsons
- Macular degeneration and other eye disorders affecting the cones
- Drug toxicity — chloroquine (used for malaria) can cause color blindness
- Nutritional deficiency affecting cone cell function
Change what you can
- If inherited color blindness, understand that correction is not currently possible — adaptive strategies (labeling, apps, specific lighting) help with daily life.
- For color blindness caused by eye disease or drug toxicity: treat the underlying condition — improvement is sometimes possible.
- Maintain a comprehensive vitamin-mineral supplement for overall eye health.
- Consult an ophthalmologist to rule out treatable underlying causes if color vision loss is new or worsening.
- Various color vision assistance apps and specially tinted lenses (EnChroma) may improve color discrimination for some people.

For inherited color blindness, no home remedy restores color perception — these practical strategies are the safest and most honest way to manage daily life.
How to do it ▾
Why it works: These strategies work around the eye's altered color perception rather than changing it, helping with tasks like matching clothes or reading color-coded charts.
- Label or organize items that are commonly confused by color, such as clothing.
- Use a smartphone app designed to identify colors when needed for a task.
- Use bright, natural, or daylight-balanced lighting when color distinction matters most.
- Let teachers, employers, or others know if color-coding is used in ways that could affect you.
Ongoing daily habit · As needed
Caution: Inherited color blindness cannot be reversed by diet, herbs, or any home remedy currently available. New or worsening color vision loss in an adult needs prompt evaluation — it can signal eye disease or drug-related changes, not simply inherited color blindness.
When to get help: See an eye doctor promptly for any new or worsening color vision change in an adult, or if color blindness is suspected alongside other vision symptoms.

This matters most for adults with new color vision changes, where prompt care sometimes allows real improvement, unlike lifelong inherited color blindness.
How to do it ▾
Why it works: Color vision loss that develops later in life, unlike inherited color blindness, can sometimes trace back to an eye disease, injury, or medication — identifying and addressing that cause can sometimes improve things.
- Note when the color vision change started and whether it affects one eye or both.
- List any new medications, recent illnesses, or eye injuries to mention to the doctor.
- Schedule an appointment with an ophthalmologist promptly rather than waiting.
- Follow their guidance on any underlying condition found.
One visit, then as directed · As soon as possible after noticing a change
Caution: Do not assume new color vision loss is simply age or inherited color blindness without a professional evaluation. Some causes of acquired color vision loss are time-sensitive to treat effectively.
When to get help: Seek prompt care for any sudden color vision change, especially with other vision symptoms like blurriness or vision loss.

A gentle general-health habit; it is honest that it will not restore color perception in inherited color blindness.
How to do it ▾
Why it works: Good overall nutrition supports eye tissue health broadly, though there is no dietary approach shown to restore or improve the function of the cone cells responsible for color perception once they are affected by an inherited trait.
- Eat a varied, whole-food diet with plenty of fruits, vegetables, and whole grains.
- Discuss a comprehensive vitamin-mineral supplement with a doctor if diet has gaps.
- Continue regular eye exams to monitor overall eye health.
- If color blindness follows an illness, injury, or new medication, mention this diet change to your eye doctor but pursue medical evaluation as the priority.
Ongoing dietary pattern · Daily
Caution: This does not treat or reverse inherited color blindness. Do not delay seeing a doctor for new-onset color vision changes while trying dietary changes first.
When to get help: See a doctor promptly for sudden or worsening color vision changes, especially with other vision symptoms.

“Disease is an effort of nature to free the system from conditions that result from a violation of the laws of health... In case of sickness 1cause should be ascertained, 2go to work intelligently to remove the disease. 3Unhealthful conditions should be changed, 4wrong habits corrected. 5Then nature is to be assisted in her effort 6to expel impurities and 7to re-establish right conditions in the system.”
🌿 Overview
Color vision depends on six million cone cells in each eye, divided into three types sensitive to red, green, and blue light. If one or more types are faulty, color blindness results. The most common inherited form is red-green color blindness, affecting roughly 8% of men and 0.5% of women. Inherited color blindness is usually permanent, but when color vision loss results from eye disease, drug toxicity, or nutritional deficiency, there may be potential for improvement. The specific nutritional support identified is vitamin A and carotene — these support the cone cells that provide color vision.
Color blindness is a reduced ability to tell certain colors apart, most commonly shades of red and green, and less often blue and yellow. It usually results from an inherited difference in the color-sensing cells of the retina, is far more common in men, and is present from birth — so it is a variation in color perception rather than an illness, and most people with it see the world clearly in every other way.
There is no cure for inherited color blindness, and it generally requires no treatment, though awareness helps with practical situations (reading color-coded information, certain tasks), and special tinted lenses help some people distinguish colors better. The condition is identified through simple color-vision tests. It is worth noting that color vision changes that appear later in life, rather than being lifelong, can occasionally signal an eye or nerve condition and should be evaluated by a doctor.
Common signs
- Reduced ability to distinguish between certain colors
- Difficulty telling red from green (most common type)
- Difficulty distinguishing blue from yellow (less common)
- Colors appearing washed out or less vibrant than others perceive them
- Difficulty reading color-coded information or traffic signals

🍽️ Eating to help
Food is one of the gentlest medicines — small, steady changes help most.
Favor these
- Dark orange and yellow vegetables for beta-carotene: sweet potato, carrot, squash
- Dark leafy greens for lutein: kale, spinach
- Eggs for pre-formed vitamin A and lutein
- Complete nutrition supporting overall eye health
Go easy on
- Refined and processed foods that deplete fat-soluble vitamins
Vitamin A and carotenoids are the primary nutritional supports for cone cell function — while they won't reverse inherited color blindness, they support optimal function of remaining color vision.
⚖️ Good to know
- Inherited color blindness cannot be reversed by any nutritional or medical treatment currently available.
- New or worsening color vision loss in an adult is a red flag — it can signal serious eye disease or drug toxicity and needs prompt evaluation.
- Color blindness can be a safety issue in certain professions (pilots, electricians, surgeons) — know the requirements for your work.
