I apreciate all the input. I called the Eye Clinic where I got my prescription and talked to them. They told me I should be fine shooting Iron sighted Rifles and Shotguns with my new prescription, but that If I find that I would like a single prescription for shooting they would write me another prescription free of charge. I feel alot better now and really like the care I recieved from the Optomitrist and Staff. They are first rate. Again Thanks.
