People with heart-shaped faces need sunglasses that harmonise with the lower part of their face, ensuring that it doesn't seem too pointed. Large lenses and soft, sinuous lines are recommended. For example, aviator models with slightly drooping lenses tend to fit perfectly with this facial shape. In any case, it's best to avoid severe, geometric shapes that fail to complement the wearer's facial features.

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.
