There should be an announcement on the label telling you the way a lot UV safety the sunglasses have.

Through a means of ionization, a skinny but extraordinarily durable movie is created on the floor of the lens. This plastic lens absorption process has been popularized by Transitions, the leading producer of photochromic lenses. Because of this, most sunglasses with photochromic lenses also have a specific amount of tint already applied to them. By immersing plastic lenses in a chemical bath, the photochromic molecules are actually absorbed to a depth of about one hundred fifty microns into the plastic.
