I strongly believe that the more you shoot the less you will close your eye. It's all about practice.
I agree with Tator , can't get enough practice.
Agreed, but once you develop that habit or a flinch, it's hard to cure. You need to practice without ammo (use snap-caps) until you get over that "expectation" of the recoil. Once the hammer let-off becomes a surprise, you'll flinch or close your eyes too late to affect your accuracy.
