More Information
Summary:An ultraviolet radiation absorbing contact or intraocular lens and method of making the same, comprising a polymeric lens material to which is covalently bonded at least one halotriazine reactive ultraviolet radiation absorbing agent of the formula wherein A and E2 are ultraviolet radiation absorbing groups which are either identical to or dissimilar to each other, or of the formula IB wherein X is Cl or F; A is an ultraviolet radiation absorbing group; and E1 is an aqueous soluble group.
