Abstract:
     The invented artifieal crystal of eyeball has lens which can absorb ultraviolt ray. It is made with the following composition (wt.%): Utraviolt ray absorbing material of 4-alkoxyl-2-hydroxybenzophenone or tetrahydroxybenzophenone 1.65-3.0. Fat soluble colouring agent 4-(2,4-xylylazo-5-mehtyl-2-phenyl-1,2,3-triazole 0.11-0.016 Orthoxylidic acid dibutyl ester 4.8-5.0.Polymethylmehtacrylate as the remainder. The composition of artifical crystal (lens) can gaint its spectral property which corresponds to the natural eyeball crystal of human being whose age is over 25 years.
