Wore glasses for 38 yrs (2nd grade). Who would've known that cataracts would be a wonderful thing? I have a severe eye phobia, but got through it. Can see great, 3D and High Def. No fogging and dirty glasses anymore. My shooting has improved too. Still need the readers, and make sure you get the right readers for the distance from your eyes to the ground (I need a 2.0 for reading, but a 1.0 will be better for trailing). I found that after shooting a doe last year, I couldn't find any blood. My readers were for close up, but my eyes were corrected for distance. That span between the readers and the ground (4-8') was still a little blurry. I found the deer just by walking towards where she ran, but would rather have followed a blood trail.
