Lens Coatings: Anti-Reflective, Mirror & Oleophobic Explained

Quick answer: Coatings are thin layers on the lens that improve vision, durability and comfort. The main ones: anti-reflective (fewer reflections), mirror (less brightness + style), oleophobic/hydrophobic (repels oils & water) and anti-scratch (durability).

Anti-Reflective (AR)

Reduces reflections on the lens surface. On sunglasses it cuts the annoying glare coming from the back of the lens; on prescription glasses it improves night vision and reduces the halos around lights.

Mirror

The reflective coating that gives the signature mirrored look. Beyond the style, it further reduces the brightness reaching your eye - ideal for very intense light (mountains, sea, snow).

Oleophobic & Hydrophobic

They repel oils (fingerprints) and water. The result: fewer smudges, easier cleaning and clearer vision in the rain.

Anti-Scratch & UV

The anti-scratch coating hardens the surface for resistance to scratches. The UV coating ensures 100% protection where the material doesn't provide it inherently.

Careful when cleaning

Coatings are durable but not indestructible: the wrong cleaning method (paper tissue, alcohol, dry wiping) wears them down. Learn how to clean them properly in our guide: Cleaning your glasses without scratches.

Frequently asked questions: Lens Coatings Explained

What is anti-reflective coating on lenses?
It's a thin coating that reduces reflections on the lens surface, improving clarity and - on prescription glasses - night vision.
Why do some lenses have a mirror colour?
That's the mirror coating: besides the style, it further reduces the brightness reaching your eye, making it ideal for very intense light.
What does an oleophobic coating do?
It repels oils and water, so the lens gets dirty less easily (fewer fingerprints) and is easier to clean.
Do coatings wear down with the wrong cleaning?
Yes. Paper tissue, alcohol, ammonia and dry wiping wear coatings down. Clean with lukewarm water, a neutral soap and a microfibre cloth.
