This works wonders for me. Im 58 now and stopped wearing reading glasses several years ago after learning an exercise while developing my meditation skills.

Simply sit and cross your eyes about half way and keep them relaxed in an unfocused way... it's takes alot of concentration to intentionally stay unfocused in your vision.

After a few minutes you will notice that your brain starts to see things different in front of you... as you start to blend both eye's on the own, not focusing them into a point.... If successful, you will start to see 3D ish, kind of things... if you go into a meditative state then you may see hologram types of scenes overlayed in front of your regular vision.

After discovering this meditation technique i realized I had been exercising my eye's in a different way and ended up having 20.15 vision when I had them checked out a few months later.

And for anyone interested, it's kind of a sacred geometry exercise with regards to the vesica pisces. Each eye represents a 'circle' of vision'....side by side...

when you cross your eyes, cross your vision so that both eyes overlap to the center.... that makes a vesica pisces range of vision.... both eye's seeing individually at the same time, overlapping, making a third and new focal point... the combination of 2 overlapping visual ranges, creating a 'third'.

In that 'third' area, when the brain syncs up to that new 'focus' you will see things you don't normally do with regular focus.

Besides, that, yes... it will heal your vision.
