|
| In USPSA, while we don't use eye covers in a match, but a lot

| your aim.
|
| In most type of shooting, you're generally NOT closing either
| of your eyes while aiming. It's counter productive to your
| situational awareness

| on pistol, never on target) so you need to do it with one
| eye. You don't want to keep it shout as this creates

| after years of training, so simple piece of paper or plastic
| to shield the eye is enough.

|

| the gun is to your face, the blurrier either the gun or the
| target gets.
|
| If you wear glasses you can test this yourself quite easily,
| punch a small hole into a piece of paper and take your glasses
| off. At an arm's length it's obviously a field stop, because you
| can only see a very narrow solid angle through the hole. If you
| put it basically on top of your eyelashes, it still reduces the
| field of view a bit, but you'll also notice how depth of field is

| Sounds like this article was written by someone who doesn't know
