The self-tinting glasses of Zeiss contain photoactive molecules that react quickly to changing light. The lenses darken in 15-30 seconds and clear again in 5 to 10 minutes. The self-tinting glasses are extremely convenient for people who are dependent on their glasses and constantly going indoors and outdoors. The combination of two products in one makes having both glasses and sunglasses unnecessary.
