CLD affects up to 50% of contact lens wearers and a key contributing factor to this is tear film instability. The physical presence of a contact lens on the eye causes structural changes to the tears making them more susceptible to evaporation and instability, which then can lead to discomfort and reduced visual quality. Successful contact lens wear relies on maximizing normal tear function over the surface of the contact lens, making the use of lens technologies that specifically support tear film stability and comfort critical.
