Okay. I'm not familiar with commercial optics, but I'm willing to
hazard a guess that the power rating has something to do with the
shape of its curve (and thus what magnification it offers and where
its default focus is). And yeah, with UV on the tag, it probably has a
coating on it. Still, with a clear lens in your eye, your visual
receptors are going to pick up on some odd stuff: humans have some
sensors for near infrared in our eyes, since evolution takes forever
to lose details that are still partially helpful, but the yellow
lenses prevent that part of the visual spectrum from getting through.
You can see through clothing now, if you practice, just like that
video camera that got recalled a couple years back. :)
