You should look into possibly getting those lenses with a UV filter to protect your eyes. UV is extremely harmful to them and you should refrain from using it too often.
A UV filter probably won't help with the bluish light right in your eyes as that is a longer wavelength. It might tone it down a bit though... but protection is more important.

Not if the leds he has are near-uv, 390nm to 400nm, so it wont cause uv damage if they are that range, but yeah having a bright led that close isn't a great idea.

So, those are special lenses? Are they prescription? Where might one obtain them?
That's a neat effect, I'd like to see details on how you made it.
