Zeiss Anti-Fog Kit, 15ml spray + 1 microfiber

Before use, clean your glasses or the optical surface. When the surface is completely dry, spray both sides of the lenses with the anti-fog spray. Then use the microfiber to distribute the product until the lenses are dry.
Repeat the operation when the anti-fog effect diminishes. Do not wash the microfiber to preserve its effectiveness over time.
Not for contact lenses.
