#Description This is a prescription lens adapter for the Valve Index Virtual Reality Headset. #Lenses I designed it for 43mm diameter lenses that come with Zenni Optical 550021 glasses. https://www.zennioptical.com/p/metal-alloy-full-rim-frame-with-spring-hinges/5500?skuId=550021 This is how I configured my order and how much it costed. https://imgur.com/a/9R7Djac I set the PD to 60mm, trying to make the focal point centered on the lens. #Files To make your own use the STL file provided and print a pair of those. Both right and left use the same part. The SolidWorks part file is provided as well if you would like to modify the design yourself as well. #Using the Adapter The glasses have screws that you'll have to unscrew before taking the lenses out. I don't remember what screws it was, but have some small screwdrivers ready. Once the lenses are out, I suggest marking the right lens on the edge with a sharpie or something so you know which one is which. They look exactly the same. You can snap in the lenses into the adapter and turn it so the thin part of the lens faces inward when put in the headset. I used a wiping cloth to handle the lens to avoid scratching. Once the lenses are in facing the right direction, you should be able to slide it onto the headset. It might catch on face gasket, so I suggest taking the gasket off before putting it on. #Draw Backs It will decrease the FOV to a certain extent compared to when you have the display as close to your eye's as possible. This can't be avoided because it's taking physical space between your eye and the headset. But from what I could test, the lenses are big enough not to block any part of the display.
