Blue light is emitted naturally through the sun. This blue light helps keep the sleep cycle and influences the correct functioning of our memory and our mind.
However, in our day to day we are also in contact with artificial blue light. It is mainly emitted by digital devices, especially television screens, mobiles, computers and tablets. All these devices emit LED lights that contain a significant amount of blue light.
In recent years, the use of digital devices has increased considerably. Our current lifestyle makes us spend a lot of time in front of screens for much of our daily tasks. However, an excess of artificial blue light can harm our visual health.
Among the detrimental effects of this overexposure to blue light are visual stress (due to the effort our eyes have to make to focus) and difficulty sleeping (due to the reduction of melatonin, the hormone responsible for sleep). Studies indicate that the LED lights in bulbs or digital screens can also promote premature aging of the retina.
For all these reasons, experts recommend the use of prescription glasses with a blue light filter as it blocks this harmful light and prevents irritation and redness in the eyes after continued use of the computer or TV. In addition, the blue light filter can be added to all lenses, regardless of their prescription.
If you spend a lot of time every day in front of a digital screen, be it a computer, a mobile phone or a TV, the use of glasses with a blue light filter is especially recommended. However, no matter what job you have, not even your age: lenses with blue light filter are recommended for everyone.
At Visual-Click, your visual health comes first. Therefore, even if you do not need to correct your eyesight, we recommend the use of neutral lenses with a blue light filter.
