lens coating
Glass surface layer
Lens coating is a thin layer applied to optical surfaces to modify how light passes through.
Anti-reflective coatings reduce glare and improve clarity in eyeglasses and camera lenses.
Other coatings repel water, resist scratches, or filter specific wavelengths: My glasses have blue-light coating.
Most quality lenses now feature multiple coatings stacked together.
- glare reductionDecreasing blinding brightness
- oleophobicRepelling oily substances
- scratch resistantWon't show wear marks
- anti-reflectivePrevents light bouncing back
- sputteringParticle ejection from surfaces
