Hi Everyone,
I have a customer who purchased glasses from me about 6 months ago. I fit him with 1.67 high index plastic lenses. The base curve of the demo lenses in the frame were 6. The customer liked the "wrap around" feel of the glasses and so I had his RX ground on a steeper base curve (clocked at 5 at dispense) than he was previously wearing (clocked at 3.5). The center thickness of his new lenses was 1 millimeter.
The RX is:
OD) -6.00 -0.25 x 135
OS) -4.25 -2.00 x 180
He brought the glasses in a few weeks ago because they'd become more curved causing blurred vision. The lenses HAVE in fact become more curved. The right lens clocks at 6.25 and the left 8.5. Any thoughts as to why the lenses (especially the left) would curve so much more than the original curve of the frame??
The lab is suggesting new lenses (same material) with a center thickness of at least 2 mm.
I'm just wondering if anyone else has had this problem and what your thoughts are.
Thanks,
Hip Chic
