Lunettes anti-lumière bleue

Natural light has various coloured wavelengths. Blue light is a portion of the light wavelength that can be seen by human eyes. In our everyday life, we are constantly exposed to blue light emitted by the sun, artificial lights, televisions and digital devices such as smartphones, tablets and computer screens.

Blue light is responsible for regulating the circadian rhythm of our bodies, which is our sleep-wake cycle. Moderate exposure to blue light can be beneficial in the daytime as it keeps us awake, but overexposure to it can become harmful, especially at night as it impedes our sleep. Overexposure to artificial blue light emitted from computer screens and other digital devices can have side effects such as eye strain, blurry vision, dry eyes, headaches and migraines and disruption of sleep patterns.

Blue light glasses are glasses equipped with blue light blocking lenses that contain a special filter to shield your eyes from the harmful blue light emitted by computer screens and other digital devices. Blue light glasses are available with or without prescription.

Blue light glasses, also known as computer glasses, help protect your eyes from the harmful blue light emitted by computer screens and other digital devices. Blue light glasses help reduce glare, eye strain and eye fatigue as well as improve focus, visual clarity and sleep cycles.

Blue light blocking glasses or computer glasses should be worn whenever you’re in front of a computer screen or tv screen or while using other digital devices such as smartphones, tablets and laptops.
