This will prevent discomfort, dryness, blurred vision and allergic reactions. 0 Child who can see in the dark Healthy eyes on the digital world Lenses should not be worn for longer than the recommended wearing period. The purpose of replacing contact lenses on a frequent basis is to prevent discomfort, dryness, blurred vision and allergic reactions that can result from a build-up of protein and lipid deposits on the lenses. As the deposits age and chemically change on the lens, they contribute to these irritations.
