In 2016, Johnson & Johnson Vision announced a monthly replacement SiHy lens, Acuvue Vita (senofilcon C). This material also features a Class I ultraviolent (UV) protection rating, and it blocks more than 90% of long-wave and 99% of shortwave UV rays. Accessed July 20, 2017.39. Mean age was 31 years (SD 11) and mean refractive error -4.5 D (SD 1.8). A plasma surface treatment (Nanogloss) renders the surface of PremiO lenses smooth with a low contact angle of 27 (captive bubble method, Menicon data on file). Over the past few years, CL companies have debuted technologies aimed at developing lenses with surface and bulk properties that reduce discomfort. Rose K lenses are a frequently prescribed lens design for the correction of keratoconus and irregular cornea conditions and are mostly rigid gas permeable lenses.

Pigment location on seven different daily disposable limbal ring CL materials was studied and, aside from one lens material, all tested lens materials revealed pigments on the surface.54 The pigments located on the surface of the CL will either interact with the palpebral conjunctiva or the cornea depending on location of the surface coating (front or back). The relationship between Dk, water content and modulus (modulus is depicted by the size of the bubble), As yet, no information is readily available on the performance of Avaira.
