Thanks for the replies

It will have to be a local optician so i need to learn as much as i can myself.

Glasses are not popular at my clubs, only a few rifle shooters use them, (never pistol shooters) and to be honest they wouldn't give you the time of day let alone help or advice.

I will check out the Stirton forum, thanks for that.

Im 48 and my eyes are starting to change noticeably, last couple of years i have made the move to the pound shop reading glasses in the workshop but my pistol shooting has never been as good.
A makeshift blinder has really helped me, returning to air pistol was just to keep shooting during the first lockdown but i have a renewed interest now and i would like to take it a bit more seriously.
