Why is it essential to replace contact lenses as recommended?

Replacing contact lenses as recommended is crucial for preventing eye infections and maintaining overall eye health. Contact lenses can accumulate deposits from tears, proteins, and environmental factors over time. These substances can lead to irritation and infections if lenses are worn beyond their recommended duration.

Additionally, older lenses may not provide adequate vision correction, as they can change shape or become damaged, which can compromise the fit and performance. By adhering to the replacement schedule, users can ensure that they are using lenses that provide optimal oxygen permeability and moisture, reducing the risk of complications such as corneal ulcers or other serious conditions.

Maintaining eye health is important not just for avoiding discomfort, but also for preserving long-term vision quality. Properly replacing contact lenses is a key part of a responsible eye care regimen.
