Polymerizable fused tricyclic compounds as absorbers of uv and visible light

An ophthalmic device that is a polymerization reaction product of a reactive mixture comprising:

• a monomer suitable for making the ophthalmic device;
• and (b) a fused tricyclic compound of formula I:
• wherein:
• m, n, and t are independently 0, 1, 2, 3, or 4;
• R1 R2, and R3 are independently at each occurrence H, an optional substituent, or —Y—Pg, or two adjacent R1, R2, or R3 groups, together with the atoms to which they are attached, combine to form a cycloalkyl or aryl ring optionally substituted with —Y—Pg;
• B represents a 5, 6, or 7 membered ring which is aromatic, saturated, or partially unsaturated optionally having up to three heteroatoms independently selected from O, S, N, and NR6, wherein R6 is H, C1-C6 alkyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, or Y—Pg;
• one of C and D represents a 5, 6, or 7 membered ring which is aromatic, saturated, or partially unsaturated optionally having up to three heteroatoms independently selected from O, S, N, and NR6, and the other of C and D is a 6 membered saturated or partially unsaturated heterocycloalkyl ring having at least one ring carbon atom and at least one heterogroup independently selected from O, S, NR6, SO, or SO2, the heterocycloalkyl ring being substituted at one ring carbon atom with a group of formula ═C(EWG)(R7), wherein R7 is EWG or —C(═O)-T-Y—Pg, and EWG at each occurrence is independently an electron withdrawing group;
• Pg at each occurrence is independently a polymerizable group;
• Y at each occurrence is independently a linking group;
• and
• T at each occurrence is independently a bond, O, or NR6,
• wherein the compound of formula I contains at least one Po group.
