ZEISS Sunlens AdaptiveSun
Sunglasses lenses that adapt to changing light
ZEISS AdaptiveSun Solutions are sun lenses designed to automatically adjust their colour intensity depending on UV exposure, giving full UV protection and convenience. It is available in several fashionable tints that provide protection in low to high light intensity.
How do photochromic sunglasses from ZEISS work?
From category 1 to category 3 in less than 30 seconds
During the day, we are exposed to different environments, situations and light conditions. Some sunglasses wearers struggle with clear, comfortable vision whenever light conditions change. Sunglasses lenses can either become too dark in the shade on cloudy days, or the colour tone can be too light on sunny days. We have applied technology based on photochromic properties to ZEISS Sunlens AdaptiveSun Solutions, enabling the intelligent adaptation of the lens tone depending on the level of exposure to UV radiation.
Durability over time
Keeping the photochromic properties for colour consistency
In photochromic materials, fatigue refers to the loss of reversibility of the two states. In other words, fatigue is how a lens loses its photochromic properties of fading and getting dark, over time and usage. The fatigue evaluation is made over a radiation test which simulates the product lifetime. This test shows almost no loss in photochromic power, meaning the lens tint basically doesn't vary.
