My search for a pair of Rx-able sunglasses got over when I visited the Mont Blanc service center to have my wife’s sunglasses fixed. They showed me the Liberty range from Liberty Sport, which was the closes to a pair of sporty looking glasses as a semi-visually impaired person can get.
Being Rx-able means that you can have prescription lens fit into the frames without it looking awkward and actually looking like they are a pair of sunglasses. They also have a range of magnetic accessories which make these glasses fit for a wide range of sports and hobbies like golf or biking. Standard equipment includes a semi hard carry case, a band and magnetic side covers which provide extra protection depending on the model you choose.
They have a cool range which is currently available at Kefan Optics and International Optique in Kuwait.
