Shooting glasses and rapid fire

[jer]

What kind of shooting glasses you are using in rapid fire? There is special glasses for rapid fire, but why not use normal glasses and block non sighting lens?

.............but why not use normal glasses and block non sighting lens?

If you do that remember that to comply with the rules you can only block a 30mm wide strip of the lens, not all of it.

Thinking about that rule these "rapid fire" glasses look interesting:

Probably a different definition of "rapid fire". Don't try them in an ISSF match. I think you know what would happen.
