Abstract
The present invention relates to soft contact lenses having an overall comfort preference of at least about 2 to 1 as compared to an Acuvue® contact lens and measured after one week of daily wear. The present invention further relates to a soft contact lens comprising an oxygen transmissibility greater than about 70 barrers/mm and physical properties suitable to provide wearer comfort over at least about 9 hours in at least about 80% of wearers, as measured in a randomized, double masked clinical study.
