FIG. 3.

Comparison of GSH levels in young (100 g) female rats where one eye was exposed to ultraviolet (UV) irradiation, while the contralateral eye was covered and served as the nonirradiated control. Rats were pretreated for 3 days with topical multifunctional antioxidant, topical nutraceutical Optixcare EH, or the oral nutraceutical Ocu-GLO administered daily. Lens GSH levels measured 2 days after exposure were significantly lower in the exposed eyes from either untreated or orally Ocu-GLO-treated rats compared with GSH levels in their contralateral unexposed lenses. Mean±SEM; n=5–6 rats; *P<0.05. GSH, glutathione.
