Extra-large size with NON-polarised shatterproof lenses making them very tough and durable yet light in weight.
Extra-large size with shatterproof polycarbonate lenses making them very tough and durable yet light in weight. These rectangular clip-on flip-up sunglasses protect against light impact and small airborne objects making them suitable for most outdoor activities and general sports use. Polycarbonate is less likely to fracture than regular plastic and so is perfect for rimless eyewear designs such as flip up sunglasses. Yellow lenses enhance contrast and depth perception by filtering scattered, out-of-focus blue light. They're especially effective in flat light or overcast conditions helping to increase visibility. Plus the addition of an anti-reflective coating on the back of the lenses gives sharper vision with less glare when driving at night and reduced eye strain for greater comfort during prolonged computer use.
