3D print STL file yourself using Acer and HP, but it should also work with Asus, Lenovo Explorer and Dell Visor (check Diameter=51.6mm and Height=10mm for existing lens cover). Updated version available at https://pinshape.com/items/483... This design supports diopter up to -3.75 with CR39 material or higher dipter with high index lenses. Other sizes available under my name. This order includes lens adapter for both eyes, but lenses are not included. Get a pair of compatible lenses by ordering this eyeglasses package from Zenni Optical ($10) at https://www.zennioptical.com/p... (search for 550021). Note that lens material should be CR39 and not polycarbonate because it has lower abberation value, resulting in better quality. Tested with diopter -3.75 (SPH), and should work up to -4.25. According to my research, when ordering eyeglasses above, set IPD to 69 regardless of personal IPD for optimal results. See the mounting procedure video.
