Is this just bad design of the plastic forms that are molded? BGD9009BR

Optician Knowledge:
Q: I can't comprehend some of the plastic forms that are molded. That back ridge upon   insert with even a moderately higher power lens forces you to really feather the back of the  lens to bring the temple in. Is this just bad design?


A: Good topic of the plastic forms that are molded. Is due to the fact that lab edges the lenses. Kind of kin to the labs that bend the nose pads in and leave them there when mounting lenses, especially thick ones they know you'll need to dis-mount, and trim the nasal side on the lenses before you adjust the nose pads.

I discover that if I selectively head the chassis from lens to outer most temple, and also the hold against a designated soft surface it may be forced on some symblance of symetry. Occasionally the bridge area should be re-arced also.
