Lenses, not just frames
Is Anti-Reflective Coating Worth It?
On indoor glasses, yes. On sunglasses, a back-surface AR is useful; a front-surface AR is mostly a talking point. Cheap AR that peels is worse than none.

What the coat is doing
Each plastic surface reflects a few percent of light. Two surfaces, plus a high-index bump, and you get ghosts, halos, and a spotlight on your eye in Zoom. AR is a stack of thin films that cancel some of that bounce. ‘Anti-glare’ in retail-speak is often just AR. Polarization is a different product.
Night driving is the demo that sells it. Headlight bloom drops. If your current pair is uncoated high-index, the upgrade is obvious in one evening.
Where cheap AR fails
It craze-cracks, rainbows, and starts to look like a dirty film you cannot clean — because you are cleaning the wrecked coat. That is a $15 add-on. A mid-range coat with a 2-year warranty is the one to buy. Clean it like a camera: microfibre, no paper towel — the scratch guide applies harder to coated lenses.
- Indoor clear: AR, yes
- High-index: AR, required
- Sun: backside AR, useful; front AR optional
- Blue-light marketing stacked on AR: pay for the AR, ignore the story
Photos, screens, and the rest
Uncoated lenses photograph as white ovals. Coated lenses photograph as eyes. If you are on video daily, that alone is worth $40. Screens also throw less of your own overhead lights back at you. None of this fixes blink rate or monitor height.
Questions, answered
- Does AR scratch more easily?
- A cheap one does, or it peels and looks like a scratch. A hard-coated AR is the stack you want. Still no T-shirts.
- Can I add AR later?
- Not well. It is applied to unfinished lenses. Replace the lenses.
- Is green or blue residual colour better?
- Cosmetics. Modern AR is faint green, blue, or magenta. Pick a shop that warranties the coat.
