What type of deposits are soft contact lenses most susceptible to?

Soft contact lenses are most susceptible to protein deposits primarily because these lenses are made from hydrophilic materials that absorb tears and other substances. The cornea's natural tear film contains various proteins, which can adhere to the surface of the lens over time. The accumulation of these proteins can lead to discomfort, reduced visual acuity, and an increased risk of complications like infections.

While bacteria, calcium, and fungi can also deposit on contact lenses, protein deposits are particularly common due to their nature and interaction with the lens material. Proteins can create a biofilm on the lens surface, affecting lens performance and hygiene. Therefore, recognizing and addressing protein buildup is crucial for maintaining lens health and ocular comfort.
