Sun shining? No problem. With our new clip-on, you can easily make your CASPAR glasses sun-ready without having to buy a new frame. The clip slides onto your glasses with a simple flick of the wrist. You don't have to worry about it while playing or romping – the clip-on fits perfectly and can withstand a lot. The ultra-light and thin lenses are also shatterproof and, thanks to Category 3, provide optimal protection against UV radiation. Compatible with all CASPAR frames.
