Confused by AR, AG, and AF? You’re not alone.
These three coatings solve completely different problems. Here‘s what you need to know.
| Coating | What It Does | Best For |
|---|---|---|
| AR (Anti-Reflective) | Reduces light reflection, improves contrast | Outdoor use, HDR content |
| AG (Anti-Glare) | Diffuses harsh glare with matte finish | Office lighting, reading |
| AF (Anti-Fingerprint) | Repels oil and smudges | Everyone |
What it does: Reduces reflected light from 8% to under 1%.
Result: Deeper blacks, higher contrast, better outdoor visibility.
Trade-off: None for most users. Slightly higher cost.
Choose AR if: You work near windows, watch HDR content, or want the best image quality.
What it does: Scatters light with a matte finish, eliminating sharp reflections.
Result: No more staring at overhead lights. Comfortable for long reading sessions.
Trade-off: Slight softening of image clarity. May create “sparkle” effect on low-quality films.
Choose AG if: You work under harsh office lighting or read text for hours.
What it does: Repels oil from your fingers.
Result: Screen stays cleaner. Smudges wipe off easily. Smooth touch feel.
Trade-off: Wears off after 12-18 months (Lusa’s lasts longer than standard 3-6 months).
Choose AF if: You touch your screen. (That‘s everyone.)

| Your Priority | Choose |
|---|---|
| Image quality + outdoor use | AR |
| Office lighting + reading | AG |
| Clean, smudge-free screen | AF |
| Everything | 3A (AR+AG+AF) |
For most MacBook and iPhone users: Start with AR + AF. You get the best screen quality without compromise.
Yes. That‘s 3A film—AR + AG + AF in one.
Not all products labeled “3A” actually include all three. Check the specs.
AR for outdoor and image quality
AG for office and reading
AF for everyone (non-negotiable)
