Q: How to trace frames with high plus lens?

A: The question "How to trace frames with high plus lens", also to Harry A Saake regarding high plus lenses in narrow frames. Why frames (high curves) have a tendency to straighten out is directly proportionate on the tracer, or pattern, utilized to edge. Some devices only measure radii and circumference in what is called ‘flat state’ – non-3D. This makes the ‘A’ measurement too much time for that bent frame. Best bet is usually to bend the frame first, then trace (or cut a pattern whichever way you do it) and then the ‘A’ measurement will be in alignment while using physical dimensions in the frame. You can even correct with this manually, by edging slightly large, then sizing by only taking out the excess over the long dimension – the 180 or ‘A’ length.
