Science behind the danger of blue light to the retina
Light is part of the electromagnetic radiation spectrum and, while vital for life on earth and necessary for vision, it carries energy that can be damaging, specifically to the region of the retina called the macula where light is best focussed. [googlepdf...
OP20 IS LIGHT WITH LACK OF RED SPECTRAL COMPONENTS A RISK FACTOR FOR AGE-RELATED MACULAR DEGENERATION (AMD)
Intense blue spectral light components pose a short-term risk to the retina, called blue light hazard (BLH). For this photochemically-induced retinal injury spectral weighting functions and applicable limit values are established. However, scientific evidence about...
