This is why we do not want to block out the whole spectrum of blue light, but rather a section of it that has adverse affects such as those coming from the artificial lighting on digital screens. That portion of artificial blue light is what can contribute to digital eye strain, can potentially increase your risk of macular degeneration, and can keep you up at night if you are on your devices close to bed time.
Previously the solution was to add an anti-reflective coating that incorporates a blue light filter. This blue light filter leaves a yellowish residual tint and reflects blue, particularly when the frame is at any angle. There were a number of people who refused this coating for it’s appearance.
For those that are aware of the dangers of blue light, but were not happy to have the yellow residual tint and blue reflection, Nikon has introduced the latest in light purification technology. The new lens, called Pure Blue UV, has molecules embedded into the lens, which filters out not only the harmful segment of blue light, but also filters out UV. This lens absorbs up to 35% of the harmful blue light.
