RE: Speciality Archery Hooded Ball Peep.
To be honest the only way you will know which one is best for you is to try them.
I suggest the same as Ausie and call them direct. If you know your prescription tell them and I bet they can match you right up.
You may also wast to ask them if there is a shop in your area that will have the different lenses for you to try or if you could order a 'set' of lenses and send back the ones that aren't needed for a refund.
