The induction of DNA photoproducts in rat corneal epithelium was studied after in vivo exposure to different doses of ultraviolet B light at 297 nm. Affinity‐purified antibodies with a major specificity against UV‐induced (6–4) photoproducts were used. The results indicate a dose dependent formation of (6–4) photoproducts. Even a minimal erythema dose (25 mJ/cm 2 ) produced (6–4) photoproducts, demonstrating that DNA damage occurs in corneal tissue following exposure to biologically relevant doses of UVB light.
