Do you shoot with one eye open and a peep? My first season of bowhunting I had the same problem: waited all season to draw on my first deer. Finally had an opportunity in the last light of the day: drew the bow, looked through the peep, and could hardly see anything.

Now I shoot with both eyes open and use a homemade contraption similar to a "hindsight" rather than a peep. Both my vision and my arrow flight (for some strange reason) are much better.
