I will be filling a new prescription shortly. I was hoping I could\nget some recommendations on what type and brand of lenses and/or AR\nI should purchase.\n\nMy prescription is as follows for both eyes:\n\n-3.50-0.75x180\n\nVisual acuity is fairly important to me, and I've heard that you\nsacrifice some of this in the higher index lenses; so I'm not certain\nwhat material (CR39, hi-index, etc) I should go with. If I should\ngo with a high index lens, which index?\n\nFor high index brands, I can select from Essilor, Optima, Pentax,\nHoya and Zeiss from between 1.56-1.71.\n\nAlso, regarding AR coatings, I've read mixed suggestions as to whether\nto apply one to a lens. It seems as though they're more practical\nwith a high index lens.\n\nFor AR coatings, I can choose from Zeiss and Crizal.\n\nAny opinions would ber appreciated. Thanks in advance.
