It does indeed , depend on the eyes ! When my eyes were 20-15 I could hit what I was aiming at , most of the time . The longer the sight plain , and the smaller the aperture , the further you will be able to hit with irons . I always use a 6:00 hold , so as not to cover my target with my front sight . Peeps were my sight of choice , when my eyes were 40 years younger .
Don't forget to have your liberals spayed or neutered !
