Figure 2. Representative photos for corneal surface evaluation among the experimental groups. A, C, and E: The corneal smoothness (A), corneal opacity (C), and lissamine green staining (E) among the five study groups were assessed for in vivo ultraviolet B (UVB) protective properties of contact lenses. The photos in the bottom row of C and E are the corresponding negative images. B, D, and F: Quantitative analysis of corneal smoothness (B), opacity (D), and lissamine green staining (F) among the five study groups (n=12 per groups) was performed. The results showed that all the scores were reduced in the groups with UVB-blocking contact lenses (Etafilcon A and HEMA+MA). The p<0.001 was determined with the Kruskal–Wallis test indicating significant difference from the UVB group. All scale bars represent 1.25 μm.
