Can I put prescription lenses in the 672/CS?

Yes. The frame is prescription-ready and accepts single-vision, progressive and multifocal lenses. The clear lenses it ships with are demo placeholders, so an optician swaps them for your prescription.

How does the clip-on attach?

The tinted front clips onto the frame magnetically and covers the lenses. You lift it off to go back to clear vision indoors.

Does the clip-on give full UV protection?

The clip-on is Category 3, the standard tint for bright daylight. It filters UV as a sunglass lens should, but only while it is attached.

Will it fit a wide head?

The frame has no spring hinges, so it flexes less than frames that do. Try it on if your head is broad or you are between sizes.

What face shapes does it suit?

The rectangular shape balances round, heart and oval faces. Square and angular faces may find it repeats their own lines.

What comes in the box?

The frame with clear demo lenses and the clip-on sunglass front, plus Marc Jacobs packaging. The packaging style varies between sets.
