I am cross eye dominant. For target, or fast moving competition shooting, it is best to let light into both eyes.
To close the dominant eye causes the open eye to dilate in response to the closed eye. This tires the eye and causes errors, especially with the long range rifle.
I squint the dominant eye so that light still enters the eye, but I don't focus on the front sight with the wrong eye.
A piece of tape over the dominant eye does the same thing, but is only good on the competition field. If I have to grab a rifle or pistol and use it in the same manner that I do on the competition field, I may not have my shooting glasses handy. Squinting works anytime and everywhere.
