Finally got my VR labs psvr lense protectors - these were the only psvr lense protector system reviewed as being worth a damn.
They have the "blue light" filter to help eye stress, and while I only tested the headset for a few moments it felt a little softer, not as stressful, kind of like when I would lower brightness some.
They are fitted in and held in place by little rubber gaskets that fit along the outside the lense and you stick down in the psVR, it's not easy and took a little to get them to really fit in and not just fall out.
They are nice, but like 30$ and from EU... but I don't have to worry about my glasses scratching the real lenses- these do seem "harder" -- like touching them they "feel" durable while the psVR lenses themselves felt "weak" if that's a thing.
