A cat eye frame made in bamboo rather than plastic or metal, with polarized TAC lenses measuring 50mm across and 44mm tall. Polarization filters the horizontally reflected light that comes off water, snow and road surfaces — the glare that a plain tinted lens does not remove.

These polarized wood frame sunglasses carry four lens treatments at once: polarized, mirrored, gradient and UV400. The supplier lists them as suitable for travel, the beach and driving, which is where polarization earns its keep.

The details

• Butterfly cat eye sunglasses
• Bamboo wood frame
• TAC lenses: polarized, mirror, gradient, UV400
• Lens width 50mm, lens height 44mm
• CE marked
• Supplied with a case; box type varies by option

Choosing a size

One frame size at 50mm lens width. The options on this listing set which case the glasses arrive in — bamboo, wooden or paper box — rather than the colour of the frame or lens.

Care

Bamboo frame with TAC lenses. Wipe the frame with a dry cloth only; bamboo is a natural material and soaking it or leaving it in a hot car will dry it out and split it. Rinse grit off the lenses under cool water before drying them with a microfibre cloth.
