Abstract
A split rim eyeglass frame mounting system is provided. The locking mechanism comprises a lens holder for surrounding and securing a rim of a ophthalmic lens. The lens holder is split at a position to define first and second portions. A locking element is disposed on the first portion and extends towards the second portion. The element includes a base and a locking portion. The base portion is disposed at a proximal end of the element adjacent to the first portion. The locking portion is disposed at a distal end of the element and is greater in width than the base portion. The locking portion includes a slot at its distal end. The slot defines oppositely disposed resilient first and second tabs. A locking compartment is disposed on the second portion. The locking compartment includes first and second cooperating recesses for receiving and securing the first and second tabs respectively.
