SUBSTANCE: invention relates to a contact lens, which is a polymerization reaction product of a reaction mixture containing a monomer suitable for the manufacture of a contact lens, and a condensed tricyclic compound selected from formulas III and V, where X represents O, S or NR⁶; Z is S; m and n are independently 0 or 1; R¹ and R² are independently at each occurrence H, C₁-C₆ alkoxy or -YP_g; R⁶ is H or YP_g; R⁷ is EWG or -C(=O)-TYP_g, and EWG is in each case independently -CN; P_g at each occurrence is independently -CH=CH₂, -C(CH₃)=CH₂; Y is independently at each occurrence a linking group selected from -O-(CH₂)₂-OC(O)-, -O-(CH₂)₃-OC(O)-, (CH₂)₃-OC(O)-CH(CH₃)-, -(CH₂)₃-OC(O)-CH(CH₃)-, -O-(CH₂)₃-OC(O)-CH(CH₃)-; and T is at each occurrence independently NR⁶, wherein the compound contains at least one P_g group.

EFFECT: obtained contact lens containing compounds that are effective for providing targeted absorption of high-energy radiation, such as UV radiation (UV-A and UV-B range), low-energy UV radiation (from 385 to 400 nm) or HEV radiation (for example, from 400 to 450 nm).
