Reflection is caused by the speed of light slowing down as it enters a transparent material. When light travels through multiple layers of different materials, and keep the light at the same speed, no new reflections are created. Racing Optics has created the SpeedStack X by optically laminating Ten layers of Tear-Offs together. The laminated Tear-Offs of the SpeedStack X displace any air in the Stack. Thus eliminating the reflections between layers. A Ten layer SpeedStack X has about the same optical characteristics as a single Tear-Off! SpeedStack Xs can be layered, giving the driver up to Thirty or more tearoffs for those long races. This allows the driver to have better visual acuity than ever experienced before from the start of a race to the checkered flag. The Smoke Stack Tear-Offs consists of three Smoke layers and four clear layers for daytime or late afternoon sessions. The Amber Stack Tear-Offs consists of one amber layer and six clear layers. Racing Optics Tear-Offs are sold in Sleeves. Each Clear Sleeve has 3 stacks of 7 or 10 layers of Tear-Offs. Sleeve contains 21 or 30 Tear-Offs total.
