[game] "IF" you can only keep "3" lens, which would they be?

Let's say you're getting rob....( by me ) ;-), but I'm generous enough to allow you to keep only 3 lens and no more.

• which 3 lens would you keep....and why?

• which 3 would I have to physically pry open from your "Dead Cold Hand?" ( Joke: referring to Charles Heston's infamous speech about guns )
