    No, not all sunglasses need to be polarized. There are some common sunglasses that can shield the eyes in sun. Of courses, sunglasses polarized are better. Compared regular sunglasses, polarized sunglasses can not only reduce strong light, prevent UV rays, but also choose filter glares from water surface, metal surface etc. This is also the reason why many fishermen and driver like to wear polarized sunglasses.
