Usually you might be accustomed to CA correction in pro photo, where you’re correcting by software the CA in realigning the R,G and B planes separately. ![]() You can mitigate some with a complex lens system like in Multi-Element Reflex Camera Lenses, or, you can mitigate by software in doing the reverse operation. This is due to the physical nature of the light traversing different medium and diffracting light to different directions depending on the wavelength. *Anti-CA Filter: any lens is creating chromatic aberrations (CA). In using this small correction this makes my eyes focusing correctly on the virtually projected image of the G2 panels and this seems to correctly put the focus at the designed distance for which they are calibrating the G2 lenses and the WMR anti-CA pre-processing filter. NB: my correction is usually +2.5 both eyes (about), and this is where using +1 does the trick: it is just a magnifying glass which makes things clear to me at about 1.0m to 1.5m distance, whereas I usually see clear past 2m to 2.5m. White lines are now white from top to bottom. Results: instant eye strain relief, clear and sharp center with the impression of a wider sharp cone in the center (it is still fuzzy as you go toward the edges but it is not appearing as much as a “clear cut”), and to top it all it is also solving the newly added WMR Anti-CA filter* which was wrongly separating the R,G and B layers too far apart otherwise. I’ve therefore decided to experiment with something: I’ve purchased low costs +1 reading glasses at the local pharmacy. Another odd things I’ve noticed is comparing side by side the Index and the G2, the image is appearing smaller to me in the later. Once I’ve tried the G2 I constantly was feeling something odd with my vision like eye straining quite quickly and as if I had strabismus. Because HMDs are usually calibrated for displaying the image at roughly 2m which I’m conformable with, I don’t wear glasses with the Index and it is really fine. I can’t see up close but can see farther away (do you call it nearsighted or farsighted?) and I’m usually wearing reading glasses. TL DR: The Reverb G2 seems calibrated for a shorter focal distance than other headsets. ![]() I wanted to start this discussion because like many others, I’ve been underwhelmed at first with the G2 “sweet spot” and I believe there are solutions like the one I’m describing below.
