Therefore, we recommend wearing blue light glasses after sunset to regulate and maintain a healthy heart rate.

Large numbers of workers suffer headaches, double vision, and migraines from long periods of the day exposed to fluorescent lights. These lights emit a noticeable amount of blue light within the range that our blue light lenses block.
