<p>Spectacles comprising spectacle mounts (a bridge piece (15) and two side pieces (29)) affixed to two lenses (2), the spectacle mounts being affixed by means of pins (25, 31) which are inserted into appropriately positioned holes or slots (28) drilled into the lenses (2). A single hole or slot (28) in the lens (2) is required to allow the attachment of each mount (15, 29) by location with the appropriate pin (25, 31). The holes or slots (28) are sized to match the dimensions of the pin to give the pins (25, 31) a“close”fit, and the adhesive is specifically chosen to act as a buffer between the pins (25, 31) and the lens (2), thereby substantially reducing or even eliminating the pressure around the assembly point which produces stress marks in rimless spectacles constructed using known methods.</p> |
