to wear for long periods of time, appropriate soft contact lenses

机译:长时间佩戴,适当的软性隐形眼镜

摘要

The present invention relates to a soft contact lens, and provides a contact lens which shows small and stable contact angle to water at its surface in water as well as in air, little deposition in wearing, high oxygen permeability, no adhesion of lens to a cornea and superior extended-wearing characteristics. The present invention provides a hydrogel soft contact lens which has contact angle at a lens surface in a range of 10-50 DEG by the captive bubble method in water and 30-90 DEG by the sessile drop method in air, oxygen permeability of not less than 30 and water content of not less than 5%, and also a hydrogel soft contact lens consisting of a polymer comprising a hydrophilic siloxanyl monomer shown by a specified general formula.
