I tried reading glasses, but when I could see the front sight clearly I could not see the target at all.
I tried bifocals but the need to tilt my head up in order to see the front sight gave me whiplssh.
I tried having the magnification part of the lens put at the top. I got massive headaches trying to bounce between the front sight and the rest of the picture.
I tried using the stick-on reading magnifiers just on my dominant eye and found out that even though my left eye was open I was ignoring any signal coming from there.
I tried progressive lenses. Still "sweet spot" problems between the front sight and the target.
Since I am interested in carry/shooting for self defense more than any other shooting acitvity, I got edumacated on body index shooting/point shooting and practice out to 20 yards every day. (Thank goodness for lasers and the reflective qualities of crinkled aluminum foil.
) Being as good as 75% of the IDPA/IPSIC shooters is good enough for me.
stay safe.
