Does Lens Color Affect UV Protection? Here’s the Truth — OJO
When you’re choosing new sunglasses, the first thing that catches your eye is often the lens color—grey, brown, green, blue, you name it. But does the tint itself make any difference to UV protection? Short answer: no. Below we break down what lens color really does, what actually blocks ultraviolet radiation, and how to pick a pair that keeps your eyes safe and stylish.
What Lens Color Really Does
Alters colour perception – certain tints enhance or mute specific wavelengths.
Adjusts contrast – brown and green lenses can boost contrast; grey keeps it neutral.
Controls brightness – darker shades dim visible light.
Important: Tint alone does not block UV rays.
What Genuine UV Protection Means
True eye safety depends on an integrated UV filter, not on lens colour or darkness.
| Certification | What It Guarantees |
|---|---|
| UV400 / 100 % UV protection | Blocks 100 % of UVA & UVB (up to 400 nm). |
| CE Mark (EN ISO 12312-1) | Confirms compliance with European safety standards. |
No matter the colour or gradient, only lenses marked UV400 shield your eyes completely.
Dark but Dangerous: Why Uncertified Lenses Can Harm
Very dark lenses without a UV filter fool your eyes into dilating. A wider pupil lets more harmful radiation reach the retina, increasing the risk of long-term damage such as cataracts and macular degeneration.
Quick Buyer’s Checklist
Pick any tint you like for comfort and style.
Look for “UV400” or “100 % UV protection” clearly printed or etched.
Check for the CE mark to ensure EU-standard compliance.
Avoid dubious street sellers—the sun doesn’t play games.
💡 The perfect pair offers style and comfort, but above all—protection.
What Are Polarized Lenses?
Polarized lenses include an extra filter that cuts harsh glare bouncing off water, roads, or glass. The result: clearer, more relaxed vision—ideal for driving, beach days, and high-glare environments. Of course, every OJO polarized lens also carries UV400 certification for total safety.
