Smartphones, tablets, PCs and notebooks are part of our everyday lives and we can no longer imagine life without them. We spend many hours every day in front of a screen surfing the internet, reading emails, working or communicating online. In the process, our eyes perform at their best, because the screens of these devices emit significantly more blue light than many natural light sources – this can put strain the eyes.

What is blue light?

With light, we distinguish between visible light and non-visible light. Visible light has a wavelength range between 380 nanometres and 780 nanometres. Non-visible light is in the ultraviolet range (so-called UV light) and the infrared range.

Blue light is short-wave and highly energetic. However, it still belongs to the visible light range. Because of its properties, blue light is also called HEV light, "High Energy Visible Light".

What effects can too much artificial blue light have on our eyes?

Basically, our body needs blue light because it is a component of natural sunlight. It has an influence on our well-being, performance and circadian rhythm, for example. But too much UV or blue light can have a negative effect on our eyes and our health.

With the daily and often intensive use of PCs, smartphones and tablets, our eyes are more frequently exposed to artificial blue light emitted by modern displays. The longer the eyes are exposed to these light sources, the higher the strain can be. Symptoms such as eye fatigue, headaches, light sensitivity or dry eyes can occur.

How do reading glasses with a blue light filter work?

To protect your eyes during daily use of digital devices, our Palermo reading glasses are equipped with a special blue light filter. This filters out approximately 30% of the artificial blue light.

The blue light filter also reduces the glare of displays and improves contrast perception - visual comfort is increased. The lenses of these reading glasses have a slight, barely perceptible tint, but this has no effect on the natural colour perception.
