3M Photochromic safety glasses

Click2Contact

The lenses of 3M’s Photochromic safety glasses are UV reactive so they respond to the amount of ultraviolet (UV) light received - lightening or darkening as needed. With these protective glasses, there is no need for two types of eyewear.

The safety spectacles change from dark to clear in 35 s and this clear state allows 84% light transmission.

They change from clear to dark in 8 s, reducing the sun’s glare and allowing just 22% light transmission.

Features and benefits include: tough polycarbonate lens absorbs more than 99.9% UV; AS/NZS1337 Medium Impact rating; abrasion-resistant hard-coat extends lens life; durable frame with nylon brow and magnesium alloy temples; the frame’s moulded lens supports prevent the lenses from being dislodged by a strong frontal impact; spring-hinged temples for narrow/wide fit; soft, adjustable nose bridge for all-day comfort; frame design has stylish carbon-fibre pattern.
