Can I put prescription lenses in these?

Yes. The frame ships with demo lenses, and any optician can cut prescription lenses to the 49 mm eye size. Budget for lens cost and fitting on top of the frame price.

What face size do the 49-19-140 dimensions fit?

A 49 mm lens with a 19 mm bridge and 140 mm temples is a medium fit. It suits most average-width faces; narrow faces may find the frame loose and wide faces may find it tight.

Are these men's or women's glasses?

Saint Laurent lists them as unisex. The round black acetate shape is worn by both, so fit matters more than the label.

What comes in the box?

Expect the frame with demo lenses and, from a Saint Laurent stockist, a branded case and cleaning cloth. Confirm the case with the seller, since third-party listings vary.

Are these good value compared with similar designer frames?

You pay a premium for the Saint Laurent name. Comparable round acetate frames from optical brands cost far less, so buy these for the design and label, not for better optics.

Our take on the Saint Laurent Unisex 49 mm

These are Saint Laurent's round acetate eyeglasses in black, sold as a frame with demo lenses, so prescription lenses must be added by an optician. The 49 mm lens width with a 19 mm bridge and 140 mm temples is a medium fit, and the round shape reads more fashion-forward than a standard rectangular frame. The frame is listed at ShopSimon as of the page data, and the demo-lens setup means the total cost includes lens fitting on top of the frame price.
