Shedding Some Light on the Dangers of Blue Wavelengths in Your Home

Your interior lighting may be causing more damage to your eyes than you think. According to a study by the Pacific Northwest National Laboratory, Addressing the Concerns Over Blue Light by Bruce Kinzey, we are exposed to broad spectrum sources containing harmful blue wavelengths every time we turn on a light. Blue light is common to all spectrum sources, but this study found much higher levels of blue wavelengths from interior sources. “Interior sources on average appear to be much more significant in terms of likely human exposure than exterior sources,” says Kinzey.

Blue light waves are the among the shortest, highest energy wavelengths in the visible light spectrum. Overexposure to blue light may cause retinal damage and contribute to degeneration of the eye. Dangers from prolonged exposure to blue light can range from eye fatigue to increased cancer risk.

Simple ways of managing this risk include avoiding unnecessary indoor lighting or blue wavelength exposure, reducing the intensity and duration of the light output, and more. According to the DOE Sky Glow Investigation, methods that communities have implemented in their exterior lighting to avoid overlighting and combat the negative effects include eliminating uplight, reducing light output, and altering the spectral content. This control over distribution and output is thanks to the LED technology that we have today. You even have the option of controlling things like spectral content and light output in your own home by ensuring that the light products you buy are putting the safety of your eyes first.

All Crystallin study and task lights are IEC-62471 certified, meaning they are LED products that emit gentle, eye-safe light that blocks most harmful UV and blue wavelengths. The Crystallin® task and study lights use an innovative liquid-crystal based film developed by Light Polymers that reduces eye-fatigue. The Crystallin phosphor film delivers higher efficiency because this it produces 15% more blue to white light conversion over current encapsulated LEDs. A task lamp using the Crystallin Gold97 spectrum delivers an industry-leading Color Rendering Index (CRI) rating of 97.
