Are the MK1140 Cortez lenses polarized?

No. This is a fashion sunglass with standard tinted lenses, not a polarized or sport model. If you need glare control for driving or water, look at a polarized pair instead.

Will these fit a narrow face?

The adjustable silicone nose pads and slim metal frame help, and the cat-eye shape is generally forgiving. Try them on if you can, since the temples are thin and fit varies by head width.

Can I put prescription lenses in them?

The full-rim metal frame can usually be reglazed by an optician, but check with the shop first. The MK lettering sits on the lenses, so replacement lenses may lose that detail.

How do they compare with plastic cat-eye sunglasses?

They are lighter and dressier than most acetate cat-eyes, but also more delicate. Plastic frames take knocks better; this metal frame rewards careful handling.

What comes in the box?

The sunglasses themselves. A case and cleaning cloth are not listed, so plan to add your own if you want protection in a bag.

Are they good for sport or the beach?

They are aimed at everyday style, not activity. The thin frame and fashion lenses suit city wear better than running, hiking or long days in strong sun.
