I believe this to be related.I had a change in prescription for my eye glasses this year,actually right before our archery season began.Because I need glasses for distance I am now challenged by my sight pin being fuzzy(which I really don't like)and my target being clear.I may have to get a longer sight arm,although it is now quite long or find some other compromise so my pin and my target are both equally as clear.
Any suggestions or input is appreciated.
