Ok since I know there are some visual sight specialist around, I have a peculiar question. If a shooter has 20/10 vision in their dominate eye and as they get older the sight changes to 20/15 then 20/20 does this have the same relative impact as a shooter with 20/20 going to 20/25 or 20/30? Would you recommend shooting glasses?
Thanks in advance!

And I almost always recommend shooting glasses. Set to an ADD of +0.50 diopters for a rifle, or +0.75 diopters for a pistol.

Oh, oops! Belay my last!
Brain problems is when your eye sees one thing and your brain sees another ..... I thought I read 10/20 ....
I'm going back and deleting my above post, so no one gets confused.
I can't speak to the vision degeneration.
Normally, what happens as you get older is pesbiopia sets in; the lens in your eye gets harder, and you lose the ability to see up close. That is the vision loss most often associated with age. However the 20/20 scale is a distance vision scale. So even if you can't read for beans, and need reading glasses, you could still have 20/20 vision.
If your distance vision degrades, that is not an expected part of aging, but can be driven by a variety of problems: macular degeneration, detached retina, glaucoma, cateracts, and a boatload of other nasty problems.
So I think a loss of near vision is broadly experienced, and you could say thee is some comparison between people. Loss of distance vision can be caused by a bunch of things, so it is more difficult to say one is comparable to something else.

Thanks - this is for a youth shooter who (IMHO) has come on quickly as a youth. I'm not sure if it was his 20/10 vision but I suspect it helped in the beginning stages. Now that he is getting older his eye sight is changing, but not horribly bad - but changing. So if you build a position with a certain level of vision reference and get used to shooting that way, if the eye sight changes it would impact the ability, I assume?
The reason this was brought on was he has been moving outward a bit, but maintaining a consistent circular pattern around the ten. ie. shooting 9.8, 9.9, 9.7, 10.0 but a very circular pattern around the ten. I started to suspect that his vision may have been changing a bit and the clarity was not there. So we had his eyes rechecked and hes moved from 20/10 to 20/20-20/15. I've read of similar experiences with shooters who age and fuzz out a bit and just need a level of correction to bring the grouping back in.
Just some thoughts - thanks for the input.
