How safe are your sunglasses? What if the tint or the shade of the lens made it difficult to distinguish between a red traffic light and a green one? What if bubbles and cracks in the lens made it harder to see than if you weren't wearing sunglasses at all? What if the materials used in the construction of the glasses themselves were flammable and began to burn while you were wearing them?
According to experts at the Optical Laboratories Association (OLA), a trade association for the eyewear industry, the two main questions people ask when shopping for sunglasses deal with fashion (e.g., "how do they look?) and function (e.g., "are they dark enough?). In fact, most people purchase non prescription, or "fashion," eyewear without any advice from eye care professionals.
So the question remains, how safe are your sunglasses?
