Zenni says that it has found an affordable way to eliminate one of the annoyances of the Covid-19 era. The online eyewear retailer is offering lenses with an anti-fog and anti-relective coating for $12.95. Each pair comes with a lens cloth that “activates the anti-fog properties”. Lenses wiped with the cloth can “provide several hours of fog-free” use. The cloth purportedly lasts for up to 12 months or 1,000 wipes. Essential workers, the company notes, will now be able to see clearly even while wearing their requisite face masks. Zenni will be giving away 5,000 pairs of its frames with the anti-fog and anti-reflective coating to workers in the U.S. Zenni is headquartered in Novato, California.
