It can also happen with RGP lenses but usually, the small molecular structure in combination with its positively charged state easily deposits on negatively charged substrates with a high water content like soft contacts. The spongy build of soft contact lenses is more prone to accumulate little molecules like lysozyme on the lens surface. What Causes Protein Deposits on Contacts? Depending on the contact lens the surface of the lens could also be polished by your optician to get rid of the protein deposits. A switch-in with contact lens care products should be always communicated to your contact lens specialist as some of the contact lenses have coatings on them which would be destroyed with abrasive cleaners.

When protein deposits start to accumulate on the lens surface lens loses the smooth feel but starts to feel dull. Depending on the quality and quantity of your tear film in combination with the contact lens material you wear components like proteins accumulate easier on the contact lens surface.
When soft contact lenses are positioned on your eye they are surrounded by the tear film which consists of proteins, mucin, water, electrolytes, and lipids.
