Figure 1. The effect of blue light exposure on the structure of the retina in C57BL/6J mice. C57BL/6J mice were exposed to different intensities of blue light (10,000, 15,000, and 20,000 lux) for 5 days (8 h/day), and hematoxylin–eosin (HE) staining was used to evaluate the structure of the mouse retina. INL: inner nuclear layer, ONL: outer nuclear layer, GCL: ganglion cell layer. **p<0.001.
