For strain-free smartphone use
If your eyes itch and burn in the evenings, it’s a sign that too much blue light has reached the retina. Blue light means stress on the eyes and also on the body: Too much blue light inhibits the production of melatonin, our sleep hormone. Besides eye irritation, the effects include sleep disturbances, which in turn can have far-reaching effects on health. To enable you to look at the smartphone display without worrying about the harmful effects of blue light, we have developed a glass display protector with an integrated blue light filter. This blue light filter retains the normal colour brilliance and clarity of the smartphone display – unlike the blue light filter that you can set directly on the smartphone, which gives the display a yellow tint. Children likewise use smartphones: The glass display protector with blue light filter simply stays on and cannot be turned off like the filter on the smartphone.
