Anti Fog Spray, 15 milliliters ZEISS lense, glasses, glass Sports, Fitness & Outdoors
Every glasses wearer is familiar with lenses fogging up: whether from wearing a facemask, stepping from a cold environment into a warm one or just consuming a hot drink.
ZEISS AntiFOG Kit combines a spray and cloth which, when used together, can be quickly applied to both sides of the lens and provide up to 3 days of defence against fogging.
AntiFOG Kit contains:
- 1 x 15ml AntiFOG Spray
- 1 x AntiFOG Cloth (5in x 5in / 13cm x 13cm)
- 1 x Portable pouch for convenient storage
How does ZEISS AntiFOG Kit work?
Using ZEISS AntiFOG spray and AntiFOG cloth together on your lenses results in the application of a thin hydrophilic film – comparable with a temporary additional coating – on the lenses. This ensures that fine, condensed water droplets do not accumulate on the lens surface causing fogging. Due to the hydrophilic coating any moisture spreads out on the lens to form a thin even layer that does not impair visual clarity. Thanks to the cloth, this process is quick, gentle and does not damage the lens coating. If the lenses need to be cleaned again it is recommended that you repeat this lens care process using ZEISS AntiFOG kit to ensure optimum protection against fogged-up lenses.
Testing carried out in 2020 at Aalen Group Test Center
ZEISS AntiFOG performance was verified by performing the following 4 tests:
Test 1 – Optical Clarity
A lens treated with ZEISS AntiFOG is examined to ensure its retained its optical clarity.
Test 2 – Huff Test
Three large exhales of air are applied directly to a lens treated with ZEISS AntiFOG to confirm ZERO fogging.
Test 3 – Cold to Room Temperature Test
A lens treated with ZEISS AntiFOG is taken from -5° C to an environment of room temperature (25° C) and confirmed to show no fogging.
Test 4 – Warm Mist Longevity Test
A lens treated with ZEISS AntiFOG is held directly in a 50° C warm mist stream and confirmed to resist fogging (as per ASTM F659 standard). This is repeated five times a day for 3 consecutive days to confirm up to 3 days fog free vision.
