ABSTRACT:
Apparatus and methods for making spectacle lens patterns are disclosed. The apparatus uses a router (or similar) bit, a spring-loaded, adjustable follower, and an existing lens (or pre-cut model) to produce patterned blanks either identically or proportionally sized to corresponding template or model lenses. The router bit rotates rapidly about its longitudinal axis as it penetrates the slowly rotating blank, producing a smooth pattern after as few as one rotation of the blank. The cover of the invention maintains the follower and cutting bit in suitable (albeit adjustable) alignment while permitting easy access to the interior of the device for inserting and removing both the lens and blank. A chute, pouch, or chip containment cavity may also be included to receive the by-products of the cutting operation for easy disposal.
