What Is Colour Blindness?

Colour blindness (colour vision deficiency) occurs when the cone cells in your eyes do not detect all three primary colours — red, green, and blue — equally. When the light-sensitive pigments in one type of cone are imbalanced or absent, the brain cannot distinguish between certain colour pairs.

The most common form is red-green colour deficiency, which affects approximately 8% of men and 0.5% of women worldwide. People with this condition are not truly "blind" to colour — they see colours, but certain shades of red and green appear very similar or indistinguishable.

Common Challenges

  • Difficulty distinguishing ripe from unripe fruit
  • Trouble reading colour-coded maps, charts, and graphs
  • Confusing traffic light colours in certain lighting conditions
  • Challenges in careers that require accurate colour perception (electricians, pilots, graphic designers)
  • Difficulty choosing coordinated clothing colours

How Colour Enhancement Lenses Work

Colour enhancement lenses use specialty optical tints that selectively filter specific wavelengths of light. In red-green colour deficiency, the red and green cone sensitivities overlap more than they should. The enhancement tint blocks the overlapping wavelengths, allowing the brain to more clearly differentiate between the two.

The result is immediately noticeable for most wearers — colours appear richer, more vivid, and more distinct. Many people describe the first time as an emotional experience, especially when seeing autumn leaves, flowers, or sunsets in full colour for the first time.

What to Expect

  • 80% success rate for red-green colour deficiency
  • Effect is immediate — you can try them in our store
  • Improvement varies by type and severity of deficiency
  • Enhancement works while wearing the lenses — not a permanent cure
  • Available as everyday glasses or sunglasses (outdoor use shows the most dramatic results)

Enhancement lenses do not work for complete colour blindness (monochromacy), which is extremely rare.

Your Colour Enhancement Options

Available with or without a prescription, in multiple formats

Prescription Enhancement Glasses

If you already wear glasses, colour enhancement tints can be applied to your prescription lenses:

  • Single vision — distance or reading correction with colour enhancement
  • Progressive — all-distance correction with colour enhancement
  • Sunglasses — outdoor use shows the most dramatic colour improvement

Non-Prescription Enhancement

If you have perfect vision but are colour deficient, we offer plano (non-prescription) colour enhancement lenses:

  • Indoor clear lenses with colour enhancement tint
  • Outdoor sunglass tint with colour enhancement — many people report the best results outdoors in natural light

Frequently Asked Questions About Colour Blindness

What is colour blindness?

Colour blindness (colour vision deficiency) occurs when the cone cells in your eyes do not detect all three primary colours equally. The most common type is red-green deficiency, affecting about 8% of men and 0.5% of women. People with it can see colours, but certain shades appear similar or indistinguishable.

How do colour blindness enhancement lenses work?

They use specialty tints that selectively filter wavelengths where your red and green cone responses overlap. By blocking the confusing wavelengths, the lenses help your brain differentiate between red and green shades more clearly. About 80% of people with red-green deficiency report significant improvement.

Do colour blindness glasses cure colour blindness?

No. Colour blindness is genetic and permanent. Enhancement lenses improve colour differentiation while you wear them, but the effect is not permanent. When you remove the glasses, your colour vision returns to baseline. They are a tool for better colour perception, not a cure.

Can I get colour enhancement lenses with a prescription?

Yes. Colour enhancement tints can be applied to any prescription type — single vision, bifocal, or progressive. They can also be made as sunglasses, which is where many people notice the most dramatic improvement.

How do I find out if I'm colour blind?

A colour vision assessment using Ishihara plates or similar tests is included in every comprehensive eye test at Fantastic Glasses. If a deficiency is found, we can discuss enhancement options during the same visit.

Do colour blindness lenses work for everyone?

About 80% of people with red-green colour deficiency report significant improvement. Results vary by type and severity. People with complete colour blindness (monochromacy) typically do not benefit. The best way to find out is to try them in-store during a consultation.
