This glass has been tested by the professional blue ray tester. The 0 level of the blue ray tester means the blue light can penetrate the lens. The 490 level of the blue ray tester means the blue light can’t penetrate the lens. CORN blue light filter glasses do have the ability of blocking the blue light. The digital screens can emit lots of electromagnetic radiation, including ultraviolet, x-rays, gamma rays etc. CORN glasses can block most of the electromagnetic radiation and give your eyes the safer UV protection. The blue light can penetrate cornea and crystalline lens thus directly shoot the macular area, which can cause sore-eye, unsmooth-eye, eyestrain and even losing sleep.

However, CORN blue light filter glasses can cut the blue UV rays, removing eyestrain, headache and even giving you a good sleep.
