Costas lenses

[BaseballFisherman]

I have 2 pairs of 400s and 2 pairs of glass 580s. All 4 pairs have held up great. You won't notice much of a difference between the two just driving around town or watching a ball game. On the water though, the 580 lenses are game changers. It's definitely worth the extra money to get the 580s. Check out eBay because I got 2 great deals on my 580s - got them both cheaper than my 400s I bought from the store.
