Blue Blocking Readers May Save Your Eyes

Blue blocking readers may be a good pick for those who are dealing with problems related to macular degeneration. These glasses filter out some of the blue spectra of light, which is the most intense and therefore tends to cause the most ocular damage as a result. It’s also the section of the electromagnetic spectrum most associated with the production of hormones that keep people awake. Wearing these reading glasses while taking a book to bed might promote more restful sleep because less blue light translateoffs into less of this particular hormone.

They’re also useful for those who read electronic books  of tablet computers. While an e-ink display can mimic regular paper, tablets use a backlight so that you can view text on a liquid-crystal display. This extra circuit generates a ton of blue light that these special glasses will block out.
