Lehman is excellent and provides first class service and support with a broad product line.
However, as a corrected vision shooter, you may be interested in the HyDefSpex Panthers (wrap around lens) system that holds a single set of corrective lens clipped inside of the tinted wrap around lens...you only have to buy/replace one pair of corrective lens and not every tint every time your prescription changes. They are expensive, but not as expensive as replacing a full set of prescription lens (I think)
