When you have a long facial shape, your choice of sunglasses should fall upon wider designs and rounded shapes which balance your facial proportions, making it seem shorter. Typically, flattering lens shapes include cat-eyes or clubmaster models, while details on top of your sunglasses will generally work really well.

Go for both! These days, sunglasses cover a huge range of products, with trendy and high-quality models varying from the most affordable to the most exclusive, and there's no need to sacrifice trendy aesthetics in favour of protection, comfort or features like polarised lenses. This year, many models are based on timeless vintage designs that combine the appeal of the past with today's technical innovations.

Research continues to develop in the world of sunglasses - something that is especially true of lens manufacturers - and every season brings news shapes, materials, details and colours onto the market. With so much choice, it's easy to find unique, trendy sunglasses. In fact, with its attention to technical details and expressive aesthetic language, the eyewear industry has never been so dynamic and full of creativity.
