Anti-glare coatings shield your eyes from external light sources, while anti-reflective coatings react to both external and internal light. Lenses with an anti-reflective coating also work better to filter blue-violet light from sunlight and indoor light. Whether you choose anti-glare or anti-reflective lenses, you’ll appreciate the benefits of reduced glare and reflections in your vision.

The primary purpose of an anti-reflective (AR) treatment for prescription eyewear lenses is to allow more light to pass through the lens and therefore reduce glare. The coating reduces reflections on the lens to reduce distractions and allow you to see more of what’s ahead of you.
