Blue light makes up about 1/3 of the visible light spectrum with the shortest wavelength and highest energy! Sunlight is the main source of blue light. Man made blue light sources include fluorescent lights, LEDs, computer screens, smartphones and computer screens. Almost all blue light passes through the cornea and lens to the retina and the effects are cumulative. Exposure to blue light can lead to macular degeneration, cataracts, dry eye, eyestrain, and sleep issues. We do need some good blue light exposure but too much of the more dangerous wavelengths can be avoided by reducing screen time (especially before bed) and with the use of blue light protection in eyewear. We have specialty lenses with blue light anti-reflection that have helped many with feeling more comfortable during their work day and sleeping at night.

So search what to do at Winnipeg’s Folklorama or check out your instagram on your smartphone at least an hour before you want to sleep. Reading print on paper is still the best choice before you shut those precious peepers.
