Sunglass frames are in every petrol station. Would it be possible to 3d-print a resin with known index of refraction, then go to town on the buffing wheel for an hour?
Would love to hear more about DIY corrective lenses.
You can get glasses from Zenni for under $10 (their website says they start at $6.95), you'd have a hard time beating their price with DIY, gas station sun glasses cost more than that around here. Of course, at that price you're not getting the lightest lenses, or coatings, but you're probably not getting that with DIY either.
