There is a handy gadget called a Sight-Blinder. These Sight-Blinders serve the same purpose as the masking tape on your favorite pair of shooting glasses, crossfire reduction. When shooting with both eyes open we don't want our non aiming eye to take over. For right eye dominate shooters this is the left eye and for left eye dominate it is the right eye.
The added advantage of this product is being able to move to the field easily without worrying about wearing your shooting glasses. This product is very basic, it consists of a small piece of metal bent at a 90 degree angle. The Sight-Blinder is attached to the barrel's vent rib using very strong two sided tape.
The Sight-Blinder attaches to any vent rib that is at least 1/4 inch wide. It can be mounted for both left and right hanged shooters; more details can be found here. There are multiple other products sold by Meadow Industries, LLC, including a fiber optic sight and Sight-Blinder in one which can be found here. There is detailed information regarding the products on the Meadow Industries website.
I've used a Sight-Blinder for skeet shooting before and was very impressed with how easy it was to keep both eyes open and on the target. My shooting improved, especially on fast moving targets and doubles where the shooter needs to pick up the second target very quickly.
I highly recommend these products they range in prices from about $15 to $30. If you don't want to spend any money or try shooting with both eyes open before making any purchases try the other method on our site for a cheaper alternative.
