The amount of downforce created by the wings or spoilers on a car is dependent primarily on two things: 1  The shape, including surface area, aspect ratio and cross-section of the device, and. 2  The device's orientation (or angle of attack).
Without a doubt, Oakley did their homework on the Prizm line. Per Drew Wallace, Product Manager with Oakley Defense, Oakley SI developed the Prizm lenses (both the TR22 and the TR45) in conjunction with the Army Marksmanship Unit, which is a group of people who know what they want and get it.
They were called Acuvue. These days there are two types of disposable soft contact lenses: daily and extended-wear. Disposable soft contact lenses do not differ from traditional contact lenses in many ways. They are made from the same materials, and both types of lens need to be replaced periodically. In the past, contact lens wearers would eventually discard their lenses.
