Look, are you shooting in high-dust environments or just worried about drops? I need to know the conditions before recommending a specific thickness. @Reply #1 - good point on the ghosting, but most people don't listen. Listen, I've tested plenty. amFilm OneTouch iPhone 16 Screen Protector is the best value. It's 9H hardness and the auto-alignment tray is foolproof. Costs $12 for two. If you want better edge protection, go with Torras Diamond Shield iPhone 16. It's $26 and rated for 8-foot impacts. The fitment is tighter for precision cases. For the lenses, avoid the unibody covers. ESR Individual Lens Protectors use tempered glass for each lens. They reduce glare better than plastic, but you're still adding a layer of glass that wasn't designed to be there. It's a trade-off between protection and 100% optical clarity.

I'm no expert but I just looked into this last week—I mean, I spent hours reading reviews—and for the screen, the Spigen Glas.tR EZ Fit is super clear and easy to line up. But for the lenses... wait, I actually found most hobbyists suggest skipping covers entirely because of that ghosting you mentioned. I'm just going with a raised-edge case like the Spigen Liquid Air iPhone 16 to keep the glass safe without the glare.
