Technical Examples
  1. The present invention relates to spherical-shaped see through lenses used in eyewear. The lenses have a substantially constant thickness and a substantially constant radius of curvature of between 28-19 mm. The spherical lenses may be supported in a frame formed of either rigid or flexible material and attached to a strap assembly adaptable to be worn by the user. Optionally, each of the lenses may be supported by a flanged member and ventilation passages preferably extending through the frame and/or the lenses to allow air to circulate around the lenses.
