When a scope is described as 3rd generation?

Question

Are we talking about the number of lenses? They are more pricey than 2nd generation.

Answer 1

I presume you are talking about night vision scopes.  The "generations" describe the electronics they use, and 3rd generation ones are more modern, work better, and are more expensive.  See Wiki for more info:
