Updated for better fit to V3 on 3/13/2019.

NEW options:

• If you have diopter between -0.50 and -3.50 (SPH) and no CYL get Small and order glasses with 1.50 standard index
• If you have diopter between -3.75 and -8.00 (SPH) and no CYL get Medium and order glasses with 1.57 mid-index
• If you have diopter has CYL get Medium and order glasses with 1.57 mid-index
• If you have diopter between +1.00 and +5.25 (SPH) get Large and order glasses with 1.67 mid-index (overall lens thickness of 5.7 mm)

Important: according to my research, when ordering above eyeglasses, the IPD (interpupillary distance) should be set to 69 regardless of your personal IPD. This way the center of eyeglasses lenses would overlap the center of Mixed Reality Headset lenses.
Before removing lenses from eyeglasses, please make sure you precisely mark the orientation of the lenses, especially if you have "CYL" in your diopter, so the lenses sit in exactly the same orientation as in the original eyeglasses.
If you have minus diopter, there is something called NV-Add, it's what you'd add to the Sphere values to get the right prescription for near vision. You can add +0.5 or +1 to your diopter to make it more comfortable for longer sessions.  This would mean if your SPH diopter is -4.5, you would order eyeglasses at -4. The headset resolution is not at eye reslolution anyway and this will also blur out the SDE a bit. This is just a suggestion. If you have questions if it will work for your diopter, contact me with Send Message button under my name.
Disclaimers : 

• I am not optitian, and doing this is at your own risk
• This is an updated version (small/large) for better fit onto headset and sides are not angled as in photo, but new version is stronger and has better fit.
• Material for Shapeways printers is more bumpy so it will look different than on video or images. New version also has a small triangle that will go to the top for easier alignment*
• White and Black available in the same material. White costs less, I did not see any difference in VR.
• Shapeways says: "The accuracy for Versatile Plastic is ±0.15 mm + 0.15% of the longest axis" so please order only if you are comfortable with a bit of sanding or using hot-glue gun, in case your print is not perfect and you need to modify it manually!

* about that triangle...
Mouting:
Large openings on the side go toward the nose
You will see a triangle on the top side, that must be aligned to the top of the headset, rotate it until the protruding tooth goes to the top about 15 degrees.
Removing the adapter:
Rotate it until the triangle goes to the top of the headset
Here is another video of explanation about the triangle, mounting and removing
