Do blue-light-blocking glasses work?

The use of screens in our day-to-day life has become commonplace. We are exposed to them for quite some time throughout the day, with their consequent adverse effects. Whether to enjoy some leisure time or search for information, we need them to work.

And that’s why you have heard of using blue blue-light-blocking glasses.

According to a study, more than 69% of screen users suffer from eye strain, commonly known as Computer Vision Syndrome. This syndrome is defined as a group of vision-related problems due to spending too much time using screens. The most common symptoms of CVS are blurred vision, dry eyes, irritation, and headaches.

One of the most widespread hypotheses is that the blue light emitted by screens causes CVS. Fortunately, various specialized lenses have been developed that reduce the transmission of blue light to the eye. They are commonly known as blue light glasses and seek to minimize the problems caused by screens. However, how do we know to what extent these filters work?

Blue light & blue light glasses

Blue light is part of the light spectrum, with wavelengths between 380 and 500 nanometers. It is emitted by the sun and artificial sources such as LED bulbs and digital screens of all kinds.

Therefore, blue light is everywhere. Natural blue light, like the sun, isn’t bad for us; it helps regulate our sleep cycle.

Artificial blue light is another story, as it can harm our vision. Therefore, people do not hesitate to opt for anti-blue light glasses to protect their eyes.

For this reason, blue-light-blocking glasses were developed to avoid any risk to the eyes.

Who can wear blue light glasses?

Anyone can! There are blue light glasses available to women, men and children.

You can use blue light glasses for any screen time activity. Whether it’s for work or studying, blue light blocking will help reduce the adverse effects of eyestrain, headaches, poor sleep and more.

If you spend many hours gaming, you’ll want to check out a pair of gaming glasses. There are blue light glasses for gamers, which tend to have a yellowish lens tint. Gaming glasses with blue light blocking allow for a better gaming experience with enhanced colours.
