Okay, after overhearing a conversation this weekend, I've done a bit of research and I have a couple of questions for the optically inclined (I am not.. lol)
I understand the relationship between diopter, focal length and power, but... when dealing with an archery lens the focal length would be the distance from your eye to the lens, I assume... does that differ if you use a straight peep or a corrected peep (clarifier installed) (do you now measure the distance to the peep from the lens, or how do you factor that into the equation)??
Next question is, how does the clarifier diopter influence the ultimate power of the lens based on it's diopter and the focal length? Is there a formula or a nomograph that can calculate this? I know the formula for calculating the ultimate power is 1/(1-D x ESI/39.37) (ESI = eye to scope/lens distance in inches(focal length))
Just trying to understand fully, so I can educate someone who is misguided..
