Did you only send this request to R. Mathews? He is correct that these three lenses are designed to be molded which he doesn’t do. Potential vendors of molded lenses would be: UL, Rochester Precision and perhaps Tower Optical. Also, we should always try to use our equivalent glasses and not our competitor’s. I understand that Mathews has no interest in working on HOYA’s supplied material. But a pressing company, would be more receptive to using our material.
By the way if you see the word “aspheres” in correspondence, the majority of the time it should be a molded/pressed product….not a grind & polish job.
