Blue-Violet Wave Sunlight

The sun gives off a natural form of blue light waves that appears blue turquoise in the visible light spectrum. This has slightly lower energy and a corresponding lower potential to cause damage. Filters in the human eye are better able to filter out this natural source of blue light, although wearing dark glasses when out in bright sunlight is recommended for prevention. So, what is the problem? Technology! The closer blue light waves fall toward the Blue-Indigo end of the visible spectrum, the more risk they pose to your eye health. These are the type of blue light waves that emit from the LED screens of computers and smartphones and tablets and so on. These highest energy blue light waves can cause the most damage to your macula. With the huge increase in LED screen time in recent decades, human eyes are being asked to handle vast amounts of artificial blue light waves, putting a serious strain on vision.
