Blue light is continuously emitted by screens (phones, computers, tablets) and
adds to the blue light already naturally present in daylight. Prolonged exposure, especially in the evening, can exacerbate eye strain: stinging, dry eyes, and a feeling of tension.
Lenses with a blue light filter help reduce the portion of light with the highest
energy, which is often responsible for glare and discomfort when looking at screens.
The result: more relaxed vision and greater comfort during prolonged use.
They can also limit the impact of artificial light on your circadian rhythm, particularly in the evening, although this effect varies from person to person.
Getting this type of lens is therefore a good idea if you spend several hours a day in front of a screen, whether for work or leisure. It’s a simple solution to improve your daily visual comfort without changing your habits.
