I have always used a true peep but went to a Specialty Archery hooded peep this year. I absolutely love this thing. The hood it great at cutting down on internal glare. It also accepts the same screw in apertures from 1/8th down to 1/32nd of an inch as well as clarifiers that may help you with your close up vision.
