But, she adds, a lack of standardization in the industry means there's no way to know if one pair is better than another. A more reliable solution: Turn on the blue-light-filtering function on your devices and limit screen time before bed. To help with eye strain,Dr Esparaz suggests ...
The higher energy and shorter wavelengths of blue light may damage your retina is the idea behind products such as blue light glasses. But there's no scientific evidence to support the theory that blue light is harmful to your eyes. Eye strain results from the way and length of time you s...
Blue-light-blocking glasses are supposed to reduce the effects of short-wavelength light from our smartphones, computer screens and LED lights: namely, eye strain (疲劳) leading to poor sleep and possibly cataracts and macular degeneration (白内障和黄斑变性). They can range from under $15 all ...
Evening exposure to short-wavelength light can affect the circadian clock, sleep and alertness. Intrinsically photosensitive retinal ganglion cells expressing melanopsin are thought to be the primary drivers of these effects. Whether colour-sensitive cones also contribute is unclear. Here, using calibrated...

Before the experiment, each of the light boxes was calibrated using a Gigahertz illuminance photometer to provide the prescribed corneal illuminance levels when subjects were positioned in the chinrest. The spectral radiances of the red and blue lighting conditions were measured prior to the ...

The 20(w) x 20(l) x 30(h) cm arena had transparent walls, blue floors, and a soft plastic roof to safely prevent mice escaping. Fecal boli were counted and presence of diarrhea were noted by a blinded experimenter at the end of each test. Mice were weighed before and after the ...
Understanding these phenomena is increasingly important as the light from modern lamps, such as LEDs, typically contains a greater percentage of blue light, making them more biologically effective, and the use of devices that emit artificial light (e.g., smartphones) becomes more pervasive4,26,...
