Are these sunglasses polarized?

No. The lenses are gray with UV protection but not polarized, so glare from water and roads is reduced only partly compared with polarized rivals.

What face size do they fit?

Calvin Klein lists a medium fit with 56 mm lenses. That suits most adult faces, but narrow faces may find them loose and very wide faces may find them tight.

Do they come with a case?

Calvin Klein eyewear normally ships with a branded case and cleaning cloth. Check the box contents with the seller if a case matters to you.

Are they good for sport?

They are listed as sport performance, but the plastic frame and fashion shape suit light activity like walking or driving. For running or cycling, a wrap-style frame with grippy temples holds better.

How do they compare with other Calvin Klein frames?

This model is a wide, plain black frame with gray lenses. Other Calvin Klein styles use metal temples, smaller lenses or different shapes, so pick this one if you want maximum coverage in a simple design.
