Sunglasses Category Info
London Mole's sunglasses, or pretty much anyone's sunglasses, are not suitable for driving in twilight or at night, and they are not suitable for looking directly at the sun. They are also not suitable for protecting your eyes in a sunbed or solarium. And they are definitely no good for protecting your eyes against chemical or mechanical hazards. They are of course great for looking dashing in.
Sunglass lenses are graded into categories depending on how much protection they offer, so when you are investing in new sunglasses you know exactly what you are getting. The lower the category level the less protection your eyes will have from the sun's harmful rays, so consider that. Here is an overview of the categories. You can find the category of our lenses printed on the inside of the temples.
CAT 0 — Very limited protection from the sun
CAT 1 — Limited protection from the sun
CAT 2 — Good protection from the sun
CAT 3 — High protection from the sun
CAT 4 — Very high protection from the sun
