Will My Amber Lenses Work For Blocking Blue Light ?
So after listening to one of Dave's recent podcasts and learning about the Uvex amber-lens glasses , I thought about ordering them from Amazon . but first on a 'hunch' I checked my old sunglass stash in the basement to make sure I didn't already have something similar that might work...and bingo ! I found not one but two different pairs of sunglasses with orange/amber lenses. Obviously I'd love to be able to use one of these pair to wear after sunset to hopefully improve my sleep. The first pair is made by Wiley X and the lens is officially called 'light rust' and is polarized. They don't appear quite as dark-orangey color as the Uvex did on Amazon, but more of a lighter-orange. Definitely a high-quality lens (optically speaking). The second pair I found was padded riding glasses made or distributed by Harley Davidson. I don't think they are polarized but the lens is definitely darker (more of an amber) than the Wiley 'light-rust' lenses. Both pair are quite comfortable to wear and the padding on the HD riding glasses actually help block out more light from entering around the edges (but the Wileys are also pretty 'fitting' too, just not quite as much as the HD's).
So....my question is, how do I know which pair would work better (if at all) at blocking blue light ? Do only polarized lenses do this ? Is there a particular 'test' I should perform tonight to evaluate the two pair ? I usually like to spend a couple hours after sunset (if I'm inside at home) watching tv and/or iPad/smartphone.
Thanx much for any advice and feedback !
