Which is better for driving?

Both are polarized, which cuts glare from roads and dashboards. The Series #52's adjustable bridge keeps the lenses centered, while the TINHAO's flip-up hinge lets you lift them at tolls or in tunnels.

Which fits over thicker prescription frames?

The TINHAO TH809 is built as a wrap-around fit-over with a flexible frame and a listed 61 mm lens width. The Series #52 relies on its spring bridge and pivot arms to spread over a frame, which suits standard square glasses better than thick frames.

Is the TINHAO worth $2 more?

Only if you want the flip-up hinge. Otherwise the Series #52 gives you an adjustable fit, a hard-coated lens and a lifetime warranty for less.

The Series #52 has hard-coated lenses and a lifetime warranty, so it is the safer bet over time. The TINHAO's flip hinge is a moving part that can loosen, and it carries no written warranty.

Yes. Both are rated UV400. The Series #52 states 99.9% UV-A and UV-B protection.

Can I wear either over glasses at night?

Neither is a night lens. The Series #52 description mentions night lenses, but the product ships with polarized dark lenses, so plan to remove them after dark.
