Which coating reduces reflections on lenses?

• A. AR coating
• B. DuraVision coating
• C. Mirror coating
• D. Scratch-resistant coating

Answer: (A)

Anti-reflective coating reduces reflections by applying multiple thin layers that cancel out reflected light through destructive interference. This boosts how much light passes through the lens, lowers glare, and makes vision clearer while lenses look almost invisible. The other coatings serve different purposes—mirror coating actually increases reflectivity to create a mirrored surface, scratch-resistant coating protects the surface without changing reflections, and DuraVision is a brand name that may denote durability features rather than specifically reducing reflections.
