LensPen NLP-1 , Black

Can someone explain the difference between this and the original LensPen, which I have and use? Does some feature make it worth buying the new version?

Does this work well for eyeglasses?

Is this safe to use on ALL filters?? On one of the other product pages for this brand, it said not to use it polarizing filters.

Can I use this to clean the DSLR camera's mirror and sensor? (My Nikon D7100 has some dust on the sensor that can't be blown away with an Air Blaster)
