Claims
- 1. An ultraviolet radiation-absorbing lens comprising an effective amount of an ultraviolet radiation-absorbing agent bonded to a polymeric material selected from the group consisting of cellulose acetate butyrate and polymethylmethacrylate, said ultraviolet radiation-absorbing agent being of the formula A--NH--B,
- wherein A is an ultraviolet radiation-absorbing component, and
- wherein B is a reactive group or moiety containing a reactive group selected from the group consisting of: ##STR14## wherein X=a halogen; R.sup.4 =H or Cl;
- Y=Cl or F;
- n=1 or 2; and
- Z=a halogen, ##STR15##
- 2. The ultraviolet radiation absorbing lens of claim 1, wherein A is selected from the group consisting of p-benzoic acids, p-salicylic acids, substituted benzophenones, substituted benzotriazoles, benzoic acid esters, acrylates oxalic acid diamides, and hydroxy phenyltriazines.
- 3. The lens of claim 1 wherein A is selected from the group consisting of ##STR16## where R=H, alkyl or metal salt and
- R.sub.1 -R.sub.3 =H, alkyl C.sub.1 to C.sub.8, C.sub.1 to C.sub.8 alkoxy, halogen, nitrogen or sulfonate.
- 4. The ultraviolet radiation absorbing lens of claim 1, wherein said agent is selected from the group consisting of 4'-(3-chloropropionamido)-2-hydroxy-4-methoxy-benzophenone-5-sulfonic acid; 4'- [4"-(2-chloroethylsulfonylmethylphenyl)amido]-2-hydroxy-4-methoxybenzophenone-5-sulfonic acid; 4'-[6-(2,4,5-trichloropyriamidinyl)]-amino-2-hydroxy-4-methoxy-benzophenone-5-sulfonic acid; 4'- [6-(2,4-dichloropyrimidinyl)]amino-2-hydroxy-4-methoxy-benzophenone-5-sulfonic acid; 4-[5-(6-(2,4-dichloropyrimidinyl)]aminobenzotriazol-2-yl]-3-hydroxybenzenesulfonic acid; 4'-[4"-[2-chloroethyl sulfonylphenyl)amino]-2-hydroxy-4-methoxybenzophenone-5-sulfonic acid; and sodium or magnesium salts thereof.
- 5. An ultraviolet radiation-absorbing polymeric material of claim 1, wherein said polymeric material is a contact lens.
