OPTILABS sunglasses, £135, www.optilabs.com

Optilabs offers a wide range of road and off-road sunnies, but its forte is prescription models, which come with either standard polarised lenses or a mirror finish.

Non-prescription lenses seem steep at £135, though single-vision (£160) or bifocals (£184) are much better value.

We tested a pair with a traditionalsporty frame and standard lenses with orange tint on a long sportive ride in the Surrey Hills. The frames themselves are ultra-light and you can easily forget you’re wearing them. In changeable weather conditions they provided good protection from glare but weren’t too dark when it clouded over. Eyewear worth investigating. MC

PROS: Light, choice of options
CONS: Pricey for non-prescription
