Polarized sunglasses help with driving.
Because they reduce glare reflected from the plane. Light is usually scattered in all directions, but when it is reflected off a plane, it tends to be polarized. Light from the sun is not polarized.

More of the horizontal component will be reflected than the vertical component, so partially polarized light reflects light. Polarized lenses contain a special filter that blocks this intense reflection and reduces glare.

And some sunglasses have no role in isolating UV, so eyes are opened and let the ultraviolet light to enter, damage to the eyes. Sunglasses can hold back ultraviolet rays because a special besmear film was added on the lens, and inferior sunglasses cannot hold back ultraviolet rays, and still let lens transmittance drop seriously, making pupils larger, so ultraviolet rays can shoot in large quantities instead and then your eye is damaged.
