I had been using regular computer glasses with no Ultraviolet protection while looking at the computer screen. I don't think that I need it with a LCD screen,but the brightness of the screen is to much some times.

I remember that Mari was saying something about blue light. I should have payed more attention to the topic.

I bought a cheap black light flashlight to study the markings on the new five,ten,and 50 dollar bills,and etc. As you all know,I'm scientifically curious.
They sent a Canary Yellow pair of gargles to put over my eyes for when I use the light. This makes sense. These gargles keep UV radiation from going into the eyes.

I have two UV germ killing devices that work in the spectrum that other UV germ killing air purifiers don't work in. I guess that those people where trying to make money with a different patent using different UV wavelengths. I think that they where made in China. They may not make them anymore. I took off the covers because the fans where not working right. I left the cover off,and It started turning the cloths around it a different color. I still have a baseball cap that is one color on one side,and another color on the other side of it. It's like the UV light had a bleaching affect. The Wave length of these two devices where at a different wavelength of the other safer UV germ killing Air purifiers. So I took them out of the closet where they cannot damage cloths,and my eyes.

With these things in mind,I'm wearing a pair of flip down yellow night driving glasses,with UV protection over my regular computer glasses. I can see the keys on the key board with them so they are not to dark. BF

I guess I'm rambling to much about the subject.
