BLUE LIGHT PROTECTION

DEFEND YOUR VISION AGAINST HARMFUL BLUE LIGHT WITH OUR ADVANCED LENSES

WHAT IS BLUE LIGHT? Blue light is one of the colours in the visible light spectrum that can be seen by human eyes. Due to its relatively short wavelengths blue light carries high amounts of energy which can be harmful to our eyes especially when it is artificial. The blue light wavelength ranges from 380- 500nm. Natural blue light is important for regulating our circadian rhythm (i.e. sleepwake cycle). Workers who are exposed to excessive amounts of harmful artificial blue light via bright LEDs, fluorescent lights, screens, and digital devices can suffer an overexposure that can cause digital eye strain, retina damage, and sleep cycle disruption.

HOW DO BLUE LIGHT GLASSES WORK?

PS17 LENSES Embedded with special pigments that target only the harmful wavelengths of blue light, the PS17 Blue Light Blocker Spectacles ensure your eyes get the protection they need without compromising vision.

Our specially designed blue light glasses are equipped with advanced lens technology that can filter or completely block out the harmful blue light range, providing the ultimate protection for your eyes.
