-4.25 Prescription Lens Adapter (old) - Windows Mixed Reality

STL file only, 3D print it yourself. Tested with Acer and HP, but it should work with Asus, Lenovo Explorer and Dell Visor (please check that existing lens cover has Diameter=51.6mm and Height=10mm) 

EDIT: updated version at https://pinshape.com/items/483...

This is for diopter up to -3.75 with CR39 material, or higher dipter with high index lenses. Other sizes available with other designs under my name.

This order includes lens adapter for both eyes. Lenses are not included. Get a pair of lenses compatible with this adapter by ordering this pair of eyeglasses for $10 from Zenni Optical (Try this link for $5 off http://bit.ly/2JcVDNk and then search for 550021) https://www.zennioptical.com/p... 

Please note that lens material should be CR39 and not polycarbonate, because CR39 has lower abberation value (less color separation at the edges) and therefore better quality. Tested with diopter -3.75 (SPH), and should work at least up to -4.25. Note: 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.
