As much as anyone, when riding at night I've been disappointed by most of the lights on my bikes. So when manufacturers started replacing incandescent with brighter LEDs, I wanted in. That said, being on the other end of them is no fun, blinding in fact, even in daylight. So much so that when I got the early ferry to France on the past few tours, I was forced to buy some night vision glasses to deal with the dangerous glare. This experience and my own failing eyesight had me looking into LEDs and their effect on health in general.
Some years ago I recognised that I was getting eye strain from using my computer and looked into ways of mitigating this. I found out that apparently the eyestrain is due to the fact that TVs, monitors, Smartphones and bright white LED bulbs that are now ubiquitous in our lives, have unnatural high peaks of blue light that effect not only our eyes but also our circadian rhythm. So a couple of years ago I bought a pair of blue light blocking glasses which I used for a while and then, foolishly, put away. Recently, as an experiment, I started putting them on after dark and the results after a few days were startling. Not only did my eyes feel less strained, but my insomnia improved. I was getting 8 hours sleep instead of 4 or 5. Although I use F-Lux and Reshift on my OSs, just flipping the glasses up the glare is still pronounced. After this result I decided to start using incandescent oven light bulbs on my table lights and masked the few LEDs I had (utility lights, fridge lights, etc.) with a couple of layers of Kapton tape, which is yellow tinted and masked the blue. A bit drastic some may think, but the difference it makes is stark.
