Hockeyref said:My question is especially to those with "aging eyesight"
In case this might be something you can use, I'll mention that while in my 60's, I'm lucky that my eyesight continues to be balanced for both eyes, and I've yet to need actual prescription glasses, being able to do fine with drug store reading glasses, bumping up an increment every couple years...currently up to +2.50 diopter for reading.
And along that same line, as the sights have become softer looking, I've been able to use full size drug store glasses of +1.0 diopter that sharpen the sights enough yet still allow distance vision without distortion while hunting...and if not this year, probably next year I'll bump up to +1.25 diopters.
The added side benefit of using the full size glasses both at the range and for hunting is some degree of eye protection from debris coming out of the pan...and after using one pair for year round shooting was shocked to notice how pitted they were becoming from all the shooting debris which otherwise would have been reaching my eyes.
