Fig 7. Selective Blue-Filtering (S-BF) lens protected RPE cells from blue light irradiation-induced cytotoxicity.

Fig 7

(A) Under blue LED irradiation, S-BF lens showed significantly elevated viability compared to the UV-filtering (UVF) lens (93.4±1.4% vs 90.6±1.4%) using trypan blue (p = 0.022) assay. (B) MTT assay also revealed that S-BF lens increased cellular viability by 22.5% (p = 0.029). (n = 3, t-test, * p<0.05).
