Hi,
I just thought I'd mention another solution that has worked for me, a cheaper solution than a whole new pair of glasses. I bought some stick-on diopters and used them on one of my old pair of shooting glasses. For example:
View attachment 86944
It's not a perfect solution for everyone, but it's cheap enough to give it a try without breaking the bank. The resin lenses are stick-on and can be trimmed with a good pair of scissors if necessary. Just a thought.
I would suggest using the lens only on your dominant eye in order to see a clear sight picture, use your non-dominant eye/peripheral vision for the target.
Thank you for your indulgence,
