1 You can try a smaller peep
2 You can try moving your sight in and out this will change the diopter of the lense
3 use a clarifier this is the last thing I would try. low light will give you problems, rain is really bad. If you shoot in the cold your breath can fog it up. for just indoor they are great.
I shoot a small peep 1/16 with my 4x and this year I have had to move it out to get it to clear up eyes are getting old.
