As always, superior glasses for 1/8 the price. After several pairs of KZFOOs, I thought to order through the eye doc again bc I was struggling with small print again. The doctor quoted $800 so I had to forgo the lightweight lenses and spent $600. However those were too heavy and lenses were not made correctly so I tried KZFOO again within a year. KZFOO’s were $100 with the same specifications (progressive, non-reflective, non-fogging, for astigmatism) and with transition (auto-darkening) added. I love them. They’re perfect.
