We all know that light can be both harmful and beneficial for our vision and our overall health, especially sleeping. Natural sunlight contains both UV and blue light. We all know the dangers of UV or Ultra Violet light and we often wear sunglasses to prevent long term damage.
But, what do we know about Blue light? Blue light, which is part of tahe visible light spectrum, reaches deeper into your eye and its cumulative effect can cause damage to your retina and it is connected to the development of age-related macular degeneration, worst of all, it makes your brain wide awake when you are about to go to bed. This is a must have software for those that works late into the night for a better eye protection, health and productivity.
Effects of Blue Light on Eye Health
people are exposed to blue light via everyday technology, Blue light exposure has been shown to impact health. Some studies also suggest that chronic blue light exposure may represent a risk for the development of age-related macular degeneration and other pathologies. Animal studies have shown that age-related macular degeneration can be induced by blue-light exposure. One epidemiological study has also shown a positive correlation between sunlight exposure – a natural source of blue light- and increased risk of early age-related macular changes in humans. However, this particular association of effects from blue light is difficult to assess in humans and warrants further study.
