Or in this case, after 80! Dr. Richard Hansler, co-founder of LowBlueLights.com, featured on CNNMoney.
Richard Hansler’s “light bulb moment” happened in 2005. With over four decades of experience as a research scientist at GE, he wanted to focus on creating lighting products that wouldn’t interfere with people’s natural sleep cycles.
At age 81, he co-founded LowBlueLights.com, which makes bulbs that don’t emit blue light, eyeglasses that block blue rays from artificial lighting, and other items.
