TARIAN specializes in crafting eyewear frames and doesn't provide corrective lenses, as we are not licensed opticians. For Optical Frames: The optical frames available on our website come with placeholder lenses for display purposes. You can easily have these replaced with prescription lenses by visiting your local optician or one of our approved retailers. Find a retailer near you. For Sunglasses: Our sunglasses are crafted in France and come with high-quality organic lenses. These lenses are equipped with 100% UV protection, fall under category 3, and have an anti-glare coating on the inner side for enhanced comfort and vision.
