Sunglasses voucher codes, coupons & deals

Lens quality matters more than the frame when it comes to how well sunglasses actually work. A stylish pair with poor lenses can let through more UV light than you would expect, so it is worth deciding whether protection or looks is your priority before you start browsing. UK retailers regularly offer deals on sunglasses, and DealRobin lists the latest offers as they appear.

Check for a UV400 or CE-marked UV rating, which shows the lenses block UVA and UVB rays. Polarised lenses cut glare from water, roads and wet surfaces, so they suit driving, fishing and water sports, while non-polarised lenses come in a wider range of tints and can be better for reading phone screens. Lens category numbers (0 to 4) indicate how dark the tint is, with category 3 suiting typical UK summer sun. Frame material affects comfort and durability, from light plastics to sturdier metal, and a good fit around the nose and ears matters more than it might seem.

A hard case helps sunglasses last much longer, so check whether one is included. If you wear them for sport or driving, models with replaceable lenses or a decent warranty can be worth paying a little more for. Prices and stock change, so check the final price and terms at the retailer.
