titleOfInvention |
Method of preparing polymeric compositions for oxygen permeable contact lenses |
abstract |
Carboxylic acid esters devoid of beta hydrogens are homopolymerized or copolymerized with contact lens organic materials to form desirable contact lens materials and contact lenses. These materials have good contact lens properties, including desirable DK values, hardness, machineability and a desirable refractive index of at least 1. |
