Abstract
Design and manufacture of material for contact lenses require a balance of functionality and comfort that is not achieved in all contact lenses. Tangible Hydra-PEG™ technology helps improve the surface properties of contact lenses of any type, including customized lenses made from any material.
Tangible Hydra-PEG –is a polymer coating, 90% water, which ensures maintenance of the tear film, improvement of wettability and lubricating, as well as resistance to the deposit formation, and therefore can be especially helpful to users of rigid gas-permeable contact lenses, which are worried about dry eyes or general discomfort when worn. According to conducted studies, 69% surveyed preferred lenses coated with Tangible Hydra-PEG™ to conventional lenses due to a higher level of comfort. This technology has been approved by the FDA. Now the products of the Optimum range produced by «Contamac» company are available with innovative Tangible Hydra-PEG™ coating: Optimum Classic (Dk 26), Comfort (Dk 65), Extra (Dk 100) и Extreme (Dk 125).
