Review on 👓 Review: Select-A-Vision Unisex Optitek Tri Focus 2201 Black Demi Reading Glasses - Find Your Perfect Fit! by Jon Odom

SAV lenses with I focal length will change my attitude towards reading glasses. Reading glasses used to help, but made switching from one task to another difficult because visual acuity changed dramatically from 6 to 12 inches away. Trifocals give you a 4-foot field of view while still allowing you to rotate your eyes back to see close-ups of what may be in your hands, just as you may have experienced with prescription trifocals in the past. I don't know how they do it but I really like it. Now I only use readers when I really need to magnify something tiny.
