Optical lens coatings are microscopic layers of metal oxides, dielectrics, or chemical treatments applied to optical and eyeglass lenses to alter how they interact with light, durability, and cleanliness,
Main Types of Lens Coatings:
Anti-Reflective (AR) / Anti-Glare Coating:
Uses thin interfering layers of metallic oxides to eliminate surface reflections and glare from lights, screens, and night driving.
Scratch-resistant (hard) coating
UV protection coating
Blue-light filtering coating
Anti-fog and hydrophobic coatings
Photochromic and mirror coatings
| Coating | What it does | Worth it for |
|---|---|---|
| Anti-reflective | Cuts glare & reflections | Almost everyone; night drivers, screen users |
| Scratch-resistant | Hardens surface | Kids, active wearers, everyday durability |
| UV protection | Blocks UV light | Everyone (often already included) |
| Blue-light filter | Filters some screen light | Some heavy screen users (comfort, not cure) |
| Anti-fog / hydrophobic | Resists fog, water, oil | Commuters, cooks, outdoor use |
| Photochromic | Darkens in sunlight | People wanting one pair for indoors & out |
