See the world through rose-tinted sunglasses. Or if that gets boring try blue, green, yellow or brown. Smith's new Slider Series of sun glasses comes with interchangeable lenses allowing you to switch your shades depending on your mood, outfit or light conditions. The frames come in six funky styles with surreal names such as Toaster and Pivot. Each frame costs £80 and comes with three lens sets: brown for the brightest days, gold for overcast days and yellow for maximum visibility in poor light. Additional lenses cost from £18 a pair and are guaranteed to give 100 per cent UV protection. Oh, and they have Hydrophilic Megol nosepads, which certainly put my mind at rest.
