Abstract
A drill guide apparatus for lens workpieces, having a substantially C-shaped base and threaded screw member, is provided. The drill guide apparatus includes a threaded aperture through the C-shaped base member for receiving the threaded screw member to clamp the drill guide apparatus to a lens workpiece. The screw member includes an axial bore through its entire length. An exit aperture is provided on an opposing side of the C-shaped base member for aligning the drill guide apparatus on a pre-marked spot on the lens workpiece. With the drill guide apparatus clamped in place, accurate drilling can be achieved without damaging the workpiece.
