GP lenses don’t absorb water like soft lenses. What is the impact on contamination and preservative sensitivity?

Explanation:
GP lenses don’t absorb water, so they don’t take up tear film or cleaning solutions into the lens material. This means contaminants and preservatives are not drawn into the lens itself and are less likely to be released toward the eye from within the lens. As a result, the internal risk of contamination and preservative-related irritation is lower with gas-permeable lenses. Surface deposits and case hygiene still matter, but the likelihood of contamination and preservative sensitivity concerns being driven by the lens material is reduced with GP lenses.
