I've had several pairs of glasses from KZFOO and have been very happy with them. My most recent pair are progressive lenses and transition and blue blocking... I went all out. They're perfect! Anyone who compliments my frames I brag about KZFOO - I even got mine 2 weeks faster than my daughter who ordered hers from her optometrist's office a week before I ordered from KZFOO 😃 Yay me !!
