Sildenafil Acutely Decreases Visual Responses in ON and OFF Retinal Ganglion Cells.

abstract：Purpose:Light-emitting diodes that emit high-intensity blue light are associated with blue-light hazard. Here, we report that blue light disturbs circadian rhythms by interfering with the clock gene in the suprachiasmatic nucleus (SCN) and that suppression of blue light at night ameliorates metabolic abnormalities by c...
