Abstract
Provided herein are examples of bead worn supports, such as eyewear, configured to provide passive venting by providing pathways between a lens and a frame and/or by providing a smooth anterior profile to allow a laminar flow of air on an anterior surface of the lens. The pathways through the frame and lens of the eyewear can be configured such that they do not provide a direct path to the eye of a wearer. The headworn supports provided hemin can provide venting while reducing or preventing unwanted light, particles, or other debris from contacting the eye of the user. The headworn supports can also be configured to exhibit excellent ballistic performance.
