I bought these sunglasses because my original pair had been broken. I know that polarized sunglasses are great to protect your precious eyes. After getting them I wore these for the first time, my goodness the vivid colors I saw. Its great. For the price unbelievable. Most polarized sunglasses cost a lot and are highly expensive! I will buy again if I do need an extra pair of polarized sunglasses. Great investment, happy customer.
