To help you find the best pair of blue light glasses, we consulted three optometrists to learn more about what to look for.

The front structures of the eye—the cornea and lens—block most UV light from reaching the retina. However, blue light passes through these protective barriers almost completely unfiltered ...

Research from the American Academy of Ophthalmology shows that the amount of blue light from digital devices is significantly smaller than what we receive from the sun. A sunny day exposes us to ...

Blue eyes (and other light colors that indicate less melanin) absorb less light. Whatever light does get in through your pupil is scattered by collagen fibers, which make the eyes look blue.

Blue light is a high-energy light that the eyes absorb from computers, smartphones, LED lights, and fluorescent lights. The sun is the biggest source of blue light. On a sunny day, it's 100,000 ...

Multiple systematic reviews, including only randomized control trials, showed no reduction of eye fatigue through the use of blue light-blocking glasses, finding a lack of evidence for their use ...

The human eye converts light into electrical impulses via a series of cones, rods, and “so-called intrinsically photosensitive retinal ganglion cells” (ipRGCs). Blue light, which is emitted ...

Blue light is part of the visible light spectrum, which is what the human eye can see, explains Dr. Hogan. The visible light spectrum ranges from wavelengths of ~400 to 700 nm, and UV light has ...

People with blue eyes have brown pigment underneath their iris and blue eyes tend to be more sensitive to light, the doctor says in the post. The ophthalmologist also said that not all babies are ...

Human subjects who tested out UCLs also showed no decrease in sensitivity to visible light while wearing them. They could identify infrared light in the dark and also in daylight. Because infrared ...
