Hello,

I was researching what some people do to help make their front sight more "crisp" when shooting their AR's with iron sights only.

I found this article to be helpful: http://www.ssusa.org/articles/2015/1...or-aging-eyes/

(I hope it's ok to post that link..)

I then started digging around to see if there was such a thing as adjustable focal length glasses for sale. I didn't find anything that said "adjustable focal length" but I did find these:

http://www.amazon.com/Adjustable-Eye...+focus+glasses

Has anyone tried these? I wear contacts, but they since both eyes are slightly different yet close enough in prescription, I was prescribed the same power contacts for both eyes. When I put on my glasses, things are noticeably clearer.

I was thinking if I bought adjustable glasses, perhaps I could achieve enhanced "fixed focal length" with thee glasses.

Thoughts?
