Review on 🔍 Biconvex Lens Set: Pop-Tech High-Quality Optical Glass Lens - Bi-Convex 34mm Diameter, 45mm Focal Length Lens for Enhanced Google Cardboard VR Experience by Samantha Cortez

This review is for lenses only, not other hardware (all reviews lumped together). The lenses are great for the price, although the pupil (the size of the central part of the lens that gives you the largest area of the field of view without distortion) is quite narrow. Image quality is excellent and I've found that you want to get your eyes as close to the lens as possible to get the widest field of view (I'm using Note 5 so it should be quite large. This gives a focal length of about 35- 45mm These lenses don't have protrusions so you'll need to attach them differently than the google cardboard design, but I found they weren't particularly loose, just wedged between layers of cardboard, at least on my first iteration Finally, get the lens profile ( for google cardboard). I just scanned the code found in the customer reference images here, worked like a charm. In the end I need the actual lens parameters, but I couldn't find anything here (like lens distortion factor etc d) if I can find them , I will update them.
