So I have an early 20's client, approx -5.00DS O.U.; who decided to go for a trendy pair of $95 Warby Parker eyeglasses.
When she came back from school around Thanksgiving, her Mom brought her in and asked if I could help figure out why these were giving her such a headache and eyestrain. Rx had been verified by WP with the prescribing office (not our Rx). Rx is as she had been wearing in my eyewear, except that I used FFSV with POW Poly AR, in a much smaller sized frame (older fashion).
Here's what I found withe the WP:
1. RX correct
2. Binocular PD correct (symmetrically set...she is only 1 mm diff between her eyes)
3. Poly OC was set at frame's mid-"B" - This meant, with such a tall shape and high bridge, that her pupil was 7mm above the OC/MC.
4. Panto of frame was 0 (ZERO)
5. Wrap angle was 6 degrees
6. Lenses were non-aspheric
7. Base curve supplied was 1.25D
So, for all intents and purposes, WP eyewear was easily fully compliant with ANSI standards - so much for ANSI ensuring client satisfaction.
Here's what I did:
1. Remade in CR39 AR FF SV with POW included
2. Supplied 4.25 BASE curve (Frame bevel curve was 2.8D)
3. Use ME1200 Variable bevel mode to taper edge thickness as to prevent frame temple "splay"
4. Edge-tinted the lenses to reduce ring effect and blend with frame.
Photos are attached to tell the visual story. Will probably have to mail eyewear to school (I prefitted them). Won't know client response until next week.
Discussion.
