Will these fit my glasses?

Only if your glasses have a semi-round rim under 3 mm thick and each lens measures close to 50 mm wide by 47 mm high. Measure one lens to the outside rim of the frame. If you are between sizes, choose the next size up.

Are they really polarized?

Yes. The lenses are TAC polarized with UV400 protection, which blocks up to 100 percent of UV rays. Polarization is what removes glare reflected off roads and water.

What sizes are available?

The semi-round shape comes in 46 x 45, 48 x 46, 50 x 47, 52 x 49 and 54 x 51 mm. This listing is the 50 x 47 mm size.

What comes in the box?

The clip-on and a microfiber pouch for storing and cleaning the lenses. No case or extra lenses are included.

Can I use them over progressive or reading glasses?

Yes, as long as the frame rim is thin and the lens shape matches. The clip sits on the front of the frame, so it does not interfere with the lenses behind it.

Is $18.99 a good price?

It is the lowest new price among the three stores that carry these as of November 5, 2026. Clip-on sunglasses of this type usually run from about $15 to $30, so this sits at the low end.

About the Semi Round Shape Polarized Clip on Sunglasses

For the semi round shape to fit your glasses, your glasses need to be similar in shape with your frame rim measuring less than 3mm's thick.

Measure one lens of your glasses carefully to the outside rim of your glasses width x height.

It is very important to measure your glasses correctly. The semi round shape needs to be nearly the same shape as your glasses and the size clip-on needs to be the same as the measurement of your glasses or the next size bigger. All of our clip-on's are rated UV400 protection which is up to 100 Percent protection. We include a microfiber pouch to store clean your lenses.
