Dual’s sunnies incorporate a small bifocal lens within the main lens, which enables you to read your cycling computer if you normally need reading glasses, while barely moving your head.
Highs: Very effective bifocal sunnies
Lows: You need to get used to them
Available in +1.5, +2.0 and +2.5 diopters, they’re also useful for roadside repairs, reading maps and using a mobile – anything where blur-free vision is an advantage – without the need to carry your reading specs.
The frames are Grilamid, while the polycarbonate lenses offer 100 per cent UVA, UVB and UVC protection. As with any bifocals it’s worth wearing these for a while to acclimatise yourself to them, but their quality and effectiveness surprised and impressed us.
