Certain camera lenses boast scratch-resistant coatings that outperform traditional options. The secret lies in mimicking the remarkable protective structure found in seashells—nacre, also known as mother-of-pearl. Nacre’s strength stems from its layered composition of calcium carbonate crystals embedded in a protein matrix. These layers, stacked in a precisely organized fashion, create a strong and flexible material that can withstand significant force without fracturing.

Researchers have replicated this hierarchical structure in lens coatings, resulting in a significantly more durable and scratch-resistant finish. This innovation allows photographers to capture stunning images without worrying about the perils of daily use and potential scratches.
