Every pair of Foster Grant's is designed and manufactured to the highest possible standards, so you can be sure that they'll never let you down. We know that the sun's rays can cause damage to the skin so we take precautions in the form of sun cream. The sun's rays can also damage our eyes so you should always wear sunglasses to protect the eyes from premature ageing and illness. Our sunglasses are fitted with UV400 lenses to block out harmful rays and provide adequate levels of protection, as well as making you look good at the same time. Always look for the British Standard EN 1836: 2005 and the CE mark.

All of our sunglasses are fitted with UV400 lenses and offer the highest level of protection from the sun
