FEATURE
Enhanced alertness: Blue light exposure during daylight hours can boost attention, reaction times and mood, contributing to improved cognitive function.
Circadian rhythm regulation: Natural blue light helps synchronise our internal body clocks, promoting healthy sleep-wake cycles. This regulation is essential for overall well-being.
PROTECTIVE MEASURES IN THE WORKPLACE Given the mixed effects of blue light, it’s important for workplaces to consider protective measures, especially in environments with high levels of artificial lighting or for those that work outside.
WHEN OUR EYES ARE RELAXED, WE BLINK MORE FREQUENTLY, WHICH HELPS MAINTAIN BETTER LUBRICATION AND OVERALL EYE HEALTH.
Use of protective eyewear: Safety glasses designed to filter out a portion of blue light can help reduce eye strain and potential long-term risks. For instance, uvex offers the CBR65 and CBR23 lenses. The CBR65 lens has a lighter tint, suitable for indoor environments with harsh artificial lighting, and blocks up to 50% of blue light at 450 nm. The CBR23 lens, with a darker tint, is ideal for bright outdoor settings and offers higher blue light reduction.

In case you’re wondering, CBR stands for:
C = Contrast enhancement – The innovative CBR tints ensure better contrast helping wearers distinguish objects more clearly, improve depth perception and help reaction times which can be particularly beneficial in hazardous environments.
B = Blue light reduction – CBR23 and CBR65 provide reliable protection against blue light emissions whether from the sun or manmade digital devices and lighting.
R = Relaxed vision – Ideal for high-concentration work; both models ensure the eyes and surrounding muscles are relaxed, supporting natural functions needed to keep eyes healthy and comfortable.
CONCLUSION While blue light is essential for various physiological functions, excessive exposure, particularly from artificial sources in the workplace, can pose health risks. Ongoing research continues to explore the long-term effects of blue light, reinforcing the importance of preventive measures. Employers should assess their work environments and consider appropriate interventions, such as protective eyewear and regular breaks, to mitigate potential risks associated with blue light exposure.
