There is absolutely no way you can't see clearly through a 3/16" peep if it's in normal light and adjusted right.

Close your eyes, draw and anchor. Then open your eyes. Can you see through the peep without moving your head? If not, it needs to be adjusted to be level with your eye. After that, it might need to be adjusted to come back square to your eye.

I do hope it doesn't rotate to where it's completely backwards when it gets to your eye. I've see that before too.[:-]
