I run a HHA optimizer lite ultra DSXL-5519 on my bow and absolutely love the sight. Due to my horrible eye sight I recently put the HHA feather vision lens kit on it, 4X magnification (+.50 diopter), which did help to clear up my sight picture a good bit, but it is still rather blurry just not as bad as before. I've been told that adding a peep clarifier would clear up the remaining blurriness but I wanted a few more opinions on the matter. Any suggestions will be greatly appreciated.
