Safety Glasses

Science Olympiad has provided definitions of the various kinds of safety glasses that are to be used in SO events. However, the explanations do not provide any pictures of the glasses in question. To clear up any confusion, here is a list of URLs where you can see examples of each type of eye protection.

Class 1 or 2: The glasses in this picture have removable side-shields. When the side-shields are removed, they would classify under the first criteria. With the side-shields on, they might pass the second criteria. However, there are far better designs of class 2 glasses. Removable Side-Shields

Class 2: These are the kinds you are most likely to see in a woodshop, and are preferable to the design I mentioned above. Glasses with Permanent Side-Shields

Class 3: This picture shows goggles that have perforations along the top and sides. [http://medisson.com/products/p1/p1.1/p1.12.html Impact goggles]

Class 4: These kinds of goggles have impact resistant lenses. The circular, white vents at the "corners" of these goggles are designed to keep liquids.[http://www.aircraftspruce.com/catalog/thumbnails/09-01498.jpg Splash/Impact Goggles]

Class 5: Apparently, this class simple refers to any eye-protection that meets the ANSI standard for High Impact resistance. So, the form factor is irrelevant, as either goggles or glasses can meet this specification.

Please note that the pictures may not show glasses that are actually ANSI rated. They were merely chosen for visual similarity to the classes listed at soinc.org.
