The clip-on is a metallic structure with sunglasses that can be “put on and taken off” of eyeglasses. This allows you to add sunglasses to a single frame for eyeglasses.
You can purchase the clip-on alone if you already have the eyeglass frames you want, thus making your eyeglasses into prescription sunglasses. Or, you can buy both items at the same time: the eyeglass frames and the sunglass clip-on. In this case, the only thing left is to add prescription lenses to the eyeglasses if needed. You can do this by contacting your trusted optician.
Warranty for the clip-on: the same warranty as for sunglasses. In the case of manufacturing defects, our warranty covers your glasses up to 30 months. If your clip-on has any type of manufacturing defect, we will send you a new pair.
