I've often posted that I do not use eye protection with my 660/880nm (Red/NIR) device. More folks are now doing this and having good results. I've had PMs that concern me because there still is confusion, even though I try to make it really clear: the frequency of the light REALLY matters -- blue light WILL cause ocular problems, transient or permanent. If you use Blue light, or a combination with Blue light then you must protect your eyes.
