Toms has become something of a household name in fashion and charity circles in the past few years since the US-based company began selling canvas plimsolls with the promise of “one for one”. For each pair of shoes sold, it donates a pair of shoes to a person in the developing world.

Now with its range of eyewear, Toms has expanded on its promise. For each pair of stylish, sun-savvy glasses sold, Toms will provide sight for one person, be that in the form of prescription glasses, sight-saving surgery or medical treatment.

Not only can you feel good about your choice, you can look good – the Toms range is wide and varied, with aviator-style sunglasses sitting alongside the kind of oversized frames that would make Anna Wintour proud. From £110 at toms.co.uk.
