Crystal Optics® - Blue Light Blocking Glasses

$69.99 CAD $89.99 CAD

Crystal Optics® blue light blocking glasses are a modern unisex style that has clear lenses with Crystal Optics Lens Technology and high quality full rim acetate frames

Crystal Optic blue light lenses dramatically improves visual acuity and focus while significantly reducing eye strain and discomfort. 

This professional style is suitable to wear when working on the computer, having dinner, socializing with friends, watching TV, and when you are around artificial lighting which gives off a lot of blue spectrum light.

BLUE LIGHT – is high energy, short wavelength spectrum light from digital and artificial sources that reduces contrast and contributes to eyestrain and poor sleep quality.

DIGITAL DEVICES – are your eyes sore from looking at your computer screen, smartphone and other digital devices? Perhaps you suffer from headaches?

ARTIFICIAL LIGHTING – get comfortable, put on your Crystal Optics Glasses and enjoy your favorite shows. Television screens give off a lot of blue light. Intense blue light in the evening interferes with natural production of the “sleep hormone” melatonin.

SLEEP BETTER - too much evening exposure to blue light can throw off the body’s biological clock or circadian rhythm, and interrupt the natural process of falling asleep. Wearing quality blue light blocking glasses in the evening a few hours before bed helps reduce this negative effect. 

LOOK GREAT – your associates, family and friends will compliment you on your dynamic and classy style!
