AI Technical Summary
Technical Problem
Existing overglasses designs face issues where the brim either fails to latch properly due to insufficient extension or causes facial contact when extended too much, leading to slipping or discomfort.
Method used
The overglasses design features a brim that protrudes more at the bridge's upper edge than at the brow bars, ensuring secure attachment to the lower eyeglasses without facial contact, achieved by a specific curvature and overhang configuration.
Benefits of technology
The design effectively prevents slipping by ensuring the brim securely hooks onto the lower eyeglasses, maintaining a stable fit regardless of the shape of the underlying eyeglasses, while avoiding facial contact.
