    Default Arnette 215 Dirty Harry Sunglasses Categories

    I found an article that talks about how much light is transmitted through your sunglasses. Here's a little piece of the article:

    Transmission Rates for Sunglasses - What are they? by "Sunglasses Guy"

    The transmission rate (also called transmittance) is the percentage which describes the amount (or rate) of sunlight that will go through the lenses of your sunglasses and into your eyes. Being a percentage, they run from 0% (black as night) to 100% (clear as day). All lenses fall somewhere in between there, most being closer to 0%. Each range of transmission rates also has categories which are organized like this:

    Category 0: 80 – 100%
    Category 1: 46 – 79 %
    Category 2: 18 – 45 %
    Category 3: 8 – 17 %
    Category 4: 3 – 8 %

    Let's break it down:

    Category 0: These lenses are those which allow the most sunlight in and are commonly associated with safety goggles or eyeglasses, or when you need to see what you are doing. Other colors in this range are bright yellow and some oranges.

    Category 1 lenses can be used for most sporting events, as they will provide adequate coverage in most conditions.

    Category 2 lenses are a lot more common and better suited for sports as they do not allow too much sunlight in as to affect your vision, but allow enough in to let you see what you are doing. Most brands use category 3 lenses for a large percentage of their models as this amount of light just happens to suit sports perfectly.

    Category 3 lenses are quite dark. They are used for many different sports, where the light is so bright that you need extra coverage (e.g., snowboarding, skiing). They can be great for a day at the beach as well. Category 2 and 3 are the most common for everything from sporting to fashion.

    Category 4 lenses are so dark that less than 10% of sunlight passes through them. You cannot see the eyes of the person wearing these kinds of lenses. They are designed for conditions in which the sun will be beaming down on you. You CANNOT wear them while driving. It is not safe and is in fact illegal in many countries.

    Does that help? Did you find it entertaining and informative?

    Does anybody know what category these Arnette sunglasses fall under?

    These are some neat facts. Indeed, "entertaining and informative." I can see a guy trying to impress a girl with this info. "Hey Baby, are those Category 3 sunglasses?"
