Hapa Kristin is fixated on creating harmony in paradoxes. Serving to both correct vision and express individuality, its colored lenses are strong yet gentle, innocent yet seductive. Made from medical grade materials, Hapa Kristin’s lenses are manufactured in automated facilities in Korea using a patented Cast Molding System, in which the colored layer is sandwiched between two lens layers to prevent discoloration and ensure hygiene, comfort and stability. The brand is also known for its photochromic and blue light-blocking lenses. YesStyle is an authorized retailer of Hapa Kristin.
