As we saw not so long ago, the eye is a sensitive organ, particularly to sunlight, which needs to be protected with sunglasses, especially for young children. However, researchers discovered some time ago that blue light can have harmful effects on our eyes. This week, Mymonture explains everything you need to know about blue light, and how to protect yourself from possible risks.

What is blue light?

Blue light is the light spectrum closest to ultraviolet light, which has long been known to be harmful to the retina. Nevertheless, the eye is designed to block a large proportion of harmful UV light before it reaches the retina. Over time, however, an accumulation effect can disrupt the functioning of the eye's various components, causing keratitis and cataracts.

To protect your eyes from UV rays, it's essential to wear category 3 or 4 sunglasses (especially in the mountains).

Blue light comes not only from natural sunlight, but also from artificial light sources such as computer screens, smartphones and tablets. As we spend more and more time in front of these screens, we need to be aware of the effects blue light can have on our visual health.

What's the solution?

There's now an anti-reflective treatment available from mymonture that blocks out some of the harmful blue light. What is this treatment, and who is it intended for?

As we saw earlier, we are increasingly exposed to blue light, due to our growing exposure to various screens. Nevertheless, this blue light is necessary in small doses for our physiological cycle, and we need it to live properly. Anti-blue-light lenses don't block all the light, but only the harmful part, allowing only the light our body needs to pass through (on average, lenses block 15-20% of blue light).

Modern life also means that we spend more and more time in front of screens, and sometimes we spend as much as 10 hours of our day looking at them. Anti-blue-light treatment has therefore been developed to relieve the eyes of wearers who use screens many times a day, by limiting the amount of blue light entering the eye so that the human body can maintain a normal rhythm of functioning.
