Abstract: A golf swing training device can be easily worn by a user, without requiring any special connection mechanism or clothing item, to provide adjustably positionable sights that assist users in improving their golf swing. One goal of the training device is to keep the golfer's vision focused on the ball while taking the swing and minimize head movement, especially during the backswing. When the correct focus is established, the swing will follow, therefore enhancing muscle memory to improve the user's swing consistency. A pair of focusing rings may be flexibly connected to a mounting system. The focusing rings can be positioned to help the golfer focus on the ball while taking their swing, especially while putting. The mounting system can secure the focusing rings in the desired position during use, while being comfortable to wear.

Abstract: Eyewear can include lenses having perimeters that are customized for an intended wearer. The perimeter of the lenses can be determined based on anatomical features of the wearer's face, the wearer's field of vision, or other parameters specific to that individual. Determination of the lens perimeters can involve developing a three-dimensional model of a wearer's face and/or head, demarcating a lens perimeter over an obtained image of a user's face, or delineating the boundary of a wearer's peripheral vision. A provisional lens perimeter obtained by any of these methods may be modified in curvature and/or size to arrive at a desired final lens perimeter. Customized lenses can be fabricated based on the determined lens perimeters. The customized lenses can be assembled into completed eyewear that is customized for a wearer, for example having shapes, sizes, and designs not otherwise possible.
