The objective of a lens for ISSF type shooting is to see the front sight, not the target!
You won't have any advantage in using such a lens, and yes I believe there are legal.

A quick check of the paper reveals it would be useless for shooting. The term "telescopic" is used because it uses reflective and refractive surfaces to bend the light rays to the parts of the retina that haven't been damaged and produce a slightly enlarged image.
The "aperture" of the magnifying part of the telescopic lens is much bigger than the aperture on the rear sight so no light would actually go through the "telescopic" contact lens at all. But the central part would be able to let light through when it is switched on. It would look OK to us normal folk.
I would argue that these are not "corrective" lenses as per the ISSF definition therefore they would/should be outlawed.
But as I say, they wouldn't do what we would like them to do!!
