Are the lenses polarized?

Yes. The Swank uses polarized lenses that filter glare and pass only usable light, which sharpens clarity and eases eye strain.

Can I put a prescription in them?

They are listed as direct-fit RX, meaning an optician can fit prescription lenses into the frame. Plan on a visit to a optical shop rather than an online order.

Do they stay on during sweaty runs?

The nose and ear pieces are hydrophilic rubber, which grips harder as it gets wet. Owners report they stay in place through sweat.

How much UV protection do they give?

Full UVA and UVB protection, listed as 100 percent UV coverage.

What comes in the box?

The polarized lenses and a lifetime warranty against manufacturer defects. A hard case is not listed.

How does the Swank compare with Tifosi's interchangeable models?

The Swank is a fixed single-lens shield, so it is lighter and simpler but you cannot swap lenses for different light. Tifosi's interchangeable models trade some weight for lens options.
