Blue light is naturally emitted by the sun. This type of light helps to regulate our sleep cycle and plays an important role in the proper functioning of our memory and mind.
However, in our daily lives we are also exposed to artificial blue light. It is mainly emitted by digital devices, especially the screens of televisions, smartphones, computers and tablets. All these devices use LED lights, which contain a significant amount of blue light.
In recent years, the use of digital devices has increased considerably. Our modern lifestyle means we spend a great deal of time in front of screens for many of our daily activities. Yet excessive exposure to artificial blue light can have a negative impact on our visual health.
The harmful effects of this overexposure include visual fatigue (caused by the effort our eyes must make to focus) and difficulty sleeping (due to the reduction of melatonin, the hormone responsible for sleep). Certain studies also suggest that LED lights from bulbs and digital screens may contribute to premature ageing of the retina.
For all these reasons, experts recommend wearing prescription glasses with a blue light filter, as they block this harmful light and help prevent the irritation and redness that often appear after spending long hours in front of a computer or television. What’s more, the blue light filter can be added to any type of lenses, regardless of your prescription.
If you spend many hours in front of a digital screen – whether it’s a computer, a phone or a television – wearing lenses with a blue light filter is highly recommended. It doesn’t matter what your job is, or even your age: blue light filter lenses are suitable for everyone.
