how thick will my lenses be...?!
Question: How thick will my lenses be...?
I am trying to order glasses online and the have 4 different types of lenses you van order: 1.50 Index Plastic High Quality Lenses, 1.59 Index Polycarbonate High Quality Lenses, 1.67 Index Super-Thin, and 1.74 Index Ultra-Thin. My prescription in -3.75 for both OD and OS, OD: CYL -0.25, axis 167 and no CYL or axis for OS. So, i am trying to figure out how thick my lenses will be if i just get the 1.50 or 1.59 lenses instead of the 1.67 or 1.74. Thanks for you help :]
Answers:
How thick the finished product is depends on the dimensions of the frame. In your case, the smaller the frame the thinner your lenses will be because minus lenses are thinnest in the centre.
1.50 will be ugly, 1.59 will be adequate. 1.67 will be thinner and nicer. 1.74 is overkill in your prescription.
