Abstract: 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.

Abstract: An athletic performance and entertainment device for use on footwear, for example, children shoes. More particularly, an entertainment device which can be attached to the tongue-area of a shoe for providing feedback to a user based on the user's performance during a selected physical activity. The user selects which activity he or she wishes to perform and presses the appropriate function button on the device. The wearer then performs the selected physical activity and the wearer's performance level is indicated by LEDs disposed on the device. A speaker may also be disposed on the device to provide audible feedback to the user. The device keeps track of improvements in performance by promoting the wearer through various award levels as performance increases, until all award levels have been mastered.
