...achromatic doublet lens? Just thinking back to my much more active astro days, and wondered if anyone had been brave and tried working out any sort of viable achromat doublet type design in ophthalmic plastics as opposed to glass? Not sure if the weight/thickness would make them commercially viable. Or the cost. Or even if the slight (i assume) increase in chromatic clarity would even be appreciated by a typical human eye in average spectacle viewing scenarios.
Just wondering out loud. :D
