Chemistrie Clip-Ons are a great way to convert your glasses to sunnies. These Clip-Ons are custom made to match the shape of your lenses. Lenses come in different tints and can be polarized. They are light and very easy to use, and can fit ANY frame. The clip attaches directly onto the lens using magnetic lens technology. The magnets can be fitted into existing glasses too. Come and see first hand how these work.
