A co-worker with many years experience has stated that Hi-Index 1.67 lenses are not aspheric unless you specifically order aspheric therefore we can save money by specifying non-aspheric Hi-Index 1.67 when we order. Where this strategy suddenly came from I do not know. He also states that poly 1.0 is thinner than a 1.67 and that using these lenses exclusively will save money. I decided to put the question on this forum. Please give my co-worker your expert advice. Thank you. PS...I am all for saving money.
