How thick should an iPhone case be to prevent camera lens damage?

When buying a protective phone case, most users check the drop rating but ignore the camera lip height case measurement. This is a big mistake. The camera lenses protrude significantly from the back glass, making them the first point of contact in a flat drop.

To ensure proper lens safety, the case must feature a raised bezel around the camera cutout of at least 0.8mm (1.2mm is optimal). This ensures that even when placed on rough surfaces, the glass lens elements hover safely above scratch-causing dirt and debris.
