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.

Abstract: Water headwear can include a plurality of openings that permit water to pass through the water headwear. Further, the water headwear can include at least one rib between the openings, the at least one rib being configured to reduce drag and cause the water headwear to more easily penetrate the surface of a body of water.

Abstract: Embodiments disclosed herein include eyewear that provides controlled variable light attenuation and color enhancement based on an input received from a user, a sensor and/or a signal from a control circuit. In some embodiments, the eyewear includes an optical filter system with two or more defined filter states that are adapted to improve color vision in different environments. The optical filter system can be incorporated into a lens having any desired curvature, including, for example, cylindrical, spherical or toroidal. The lens can include one or more functional components. Examples of functional components include color enhancement filters, chroma enhancement filters, a laser attenuation filter, electrochromic filters, photoelectrochromic filters, variable attenuation filters, anti-reflection coatings, interference stacks, hard coatings, flash mirrors, anti-static coatings, anti-fog coatings, other functional layers, or a combination of functional layers.
