Buying a pair of sunglasses is an important purchase. Not only do the lenses need to give you the best possible vision, your frames need to fit well too. If you are unsure which frames will suit you, Optilabs offers a Try Before you Buy service allowing you to choose up to three frames and have them delivered to your home so you can make your choice – and ask advice from family and friends should you need to. All frame samples will be fitted with plain, non prescription lenses at this stage but you will be able to get a good idea of fit and comfort before you order. This service is currently available to UK customers only.
