In today's digital world, prolonged screen time is almost inevitable. However, the blue light emitted by screens can lead to digital eye strain and disrupt sleep patterns. Laurier Optical understands the importance of protecting your eyes, which is why we offer blue light blocking lenses. Let's delve into the science behind these lenses:

Understanding Blue Light

Blue light is part of the visible light spectrum and is emitted by digital devices like smartphones, computers, and tablets. While some exposure to blue light is necessary for regulating our sleep-wake cycle (circadian rhythm), excessive exposure, especially at night, can have adverse effects.

How Blue Light Affects Sleep

Exposure to blue light in the evening can interfere with our natural sleep patterns by suppressing the production of melatonin, a hormone that regulates sleep. This can lead to difficulty falling asleep and poor sleep quality.

Digital Eye Strain

Blue light can also contribute to digital eye strain, characterized by symptoms like eye fatigue, headaches, and dry eyes. Blue light blocking lenses work to reduce the amount of blue light that reaches your eyes, thus alleviating these symptoms.

How Blue Light Blocking Lenses Work

Blue light blocking lenses are designed to filter out or absorb a portion of the blue light emitted by screens. They use specialized coatings or materials that target specific wavelengths of blue light while allowing other colors to pass through.

Benefits of Blue Light Blocking Lenses

Blue light blocking lenses can improve sleep quality, reduce eye strain, and protect your eyes from potential long-term effects of excessive blue light exposure.
