I’ve used https://higherdose.com/products/higherdose-red-light-face-ma... for awhile now and while it is slightly lower in RED nm it does the job. Usually a 10 or 20 minute session after a shower. The bonus is you get to look like doctor doom or the man in the iron mask.
Enough red light seems to get in your eyes with this mask, but it isn’t as directed as other products.
I've seen many results with it in general. Eyesight was one I wasn't really aware of until recently. I do notice nuance in colors more than before. But I can't really say it's a night or day difference. Blacks are blacker, browns show hue better, etc.
After you do a 10 minute session for example and look at a monitor, you see significant contrasts for awhile until your eyes re-adjust. I like to think that it is doing something and is why I keep doing it outside the mood/skin/etc benefits.
