ABSTRACT:
A coating composition based upon at least partially hydrolyzed epoxy-functional alkoxy silanes and having particular utility in forming tintable, abrasion resistant coatings on lenses. Incorporation in the composition of a non-hydrolyzed epoxy-functional alkoxy silane provides a desired reduction in viscosity. Incorporation in the composition of a polyether surfactant provides a cured coating of the composition with increased tintability.
