For 1/4 of the cost that I paid a local ophthalmologist shop for the same prescription and almost the exact same shape/style these glasses are 100x BETTER. After getting the expensive local pair of transition lenses I thought... nope, not gonna be able to wear transitions. Then I got the KZFOO pair! Completely different, sooooo much better. I ordered a second pair, exactly the same because I never want to be without these glasses. Thank you KZFOO!!!!
