What factor primarily contributes to lens comfort in wearers?

Moisture retention plays a significant role in the comfort of contact lens wearers. When lenses retain moisture, they maintain hydration, which is essential for comfort throughout the day. Dry lenses can lead to discomfort, irritation, and a foreign body sensation, making it challenging for individuals to wear them for extended periods.

Additionally, the material composition of the lens significantly influences its ability to retain moisture. Lenses designed with high water content or special moisture-retaining technologies provide a more comfortable experience by ensuring that the lenses remain wet and do not dry out during wear. Therefore, proper moisture retention is essential in ensuring the comfort level of contact lenses, directly affecting the overall satisfaction of the wearer.
