what is blue light?
Blue light is everywhere, with the vast majority of it coming from the sun. Our body responds to blue light naturally. Daylight hours prompt our mood and heighten our alertness.
LED lights also emit blue light. Due to the energy efficiency of LED lights, they have been adopted by many industries, including as part of digital devices such as phones, televisions, digital screens, and digital dashboard displays. As digital devices have become a way of life, so too has the blue light they emit.

WHAT ARE BLUE LIGHT GLASSES?
Blue light glasses are also referred to as blue block glasses or blue light blocking glasses.
They are designed to block the artificial blue light emitted from digital screens through the application of a special filter to the lens.

do Blue block Glasses really work?
The effect of exposure to blue light from digital devices is currently insufficiently researched. However, some people report blue block glasses have helped relieve sleep disruptions, eye strain, and fatigue.
THE argument FOR BLUE LIGHT GLASSES
Many people express their difficulty to ‘switch off’ after hours of screen-time. Frequent use of blue light from digital devices is more focused, and blocking this will reduce adverse effects on the eye.
THE argument AGAINST BLUE LIGHT GLASSES
The sun provides an abundance of blue light, and the amount digital devices expose us to is negligible by comparison, making blue light glasses unnecessary.
