Why do spectacle lenses fog up ?
Condensation occurs on eyeglass lenses when water vapour—from your sweat, breath, and ambient humidity—lands on a cold surface, cools, and then changes into tiny drops of liquid, forming a film that you see as fog.
GOFREE Anti-Fog spray creates a coating on the lens that ensures water droplets do not stick to the lens. Hence, the lens does not fog up.
Any glasses wearer is familiar with this trouble, as foggy lenses are a common complaint. Prescription eyeglasses, athletic sunglasses, and snowboard goggles end up with condensation on the lenses at inopportune times. GOFREE Anti-Fog spray is a convenient and economical solution which keeps your lenses from fogging up for up to 24 -72 hours. (Effectiveness varies according to humidity)
