Abstract
A method of decreasing the amount of cosmetic defects in contact lenses made from hydrophilic and hydrophobic monomers. By filtering the monomer mixture with a filter, the hydrophilic and hydrophobic components are finely dispersed throughout the mixture. Dissolved gases contained within the mixture are also finely dispersed. Contact lenses produced from this method have improved optical quality.
