Newbie question: effective focusing distance

Same thing with contacts if you only have one in, it’s really easy to forget you’re only wearing one. Out of curiosity which eye did you go with the long vision on? If it was me I think I would choose the left eye since it’s probably marginally better for driving (Canada/US).

I went for long vision in the right eye but I don’t think that was because we drive on the left in Australia! The surgeon recommended it on the basis that she thought it was the “stronger” one. And I think she was right to do so as I have had no problems at all with it, while the left eye took a while to settle down.

I doubt that 5m-infinity eye will get any acceptable focus in Pimax. If it was so there would be no need for the other eye to be set to 1m-4m for real world.

The 1m-4m eye should get good focus in Pimax though. So probably glasses with correction for the eye with 5m-infinity will do fine. Or you accept limitation you have in real world - eg one eye is in focus and other is not and let the brain sort it out. Maybe try to look at some large painting or something on wall about 1.2m distance and it can get you some basic idea of what to expect in Pimax (without correction).

At this stage I’m content to wait for the empirical data (ie when the 8KX arrives). Will report though.

thanks you ! look forward to it

As someone who’s getting a bit farsighted with age and need (low strength) reading / screen glasses, I do not need any glasses in any of my VR headsets incl. the 8K, so yeah focus is somewhere on the far side of 1-1½ meter.

Keep in mind that the 8kX still just barely achieves 20/20 vision. Under less than ideal conditions (eg. roomscale or casual where the headset can get misaligned quite a bit), 20/25 or 20/30 may be more typical. And in this case, the other eye will already be perfectly focused. So it may turn out to be a reasonable set of compromises.

This is irrelevant. With heavy de-focus you just get heavy blur, no point talking about degrees of clarity. I think the main factor is that the adaptive focus lens (normally present in eye) was changed to fixed focus lens. Fixed focus simply does not work outside specified range. If I take camera with min. focus distance of say 0.5m then anything even at 0,4m distance will be unusable, 0.1m would be total mess (5m->1m should behave similarly). Of course brain can still do some magic considering other eye image is good, at least for the overlap area.

Anyway OP will try and see and decide, not much point for theory-crafting.

Indeed I will, and will report results with various corrections, including none.

Same for me. My eyesight is getting worse since a couple of years. To the point where i enjoy being able to focus sharply at anything in VR. In real life it becomes harder and harder…

haha, yeah that’s why i become a bit concerned when people are praising the idea of vari-focal lences, i mean just imagine having to put on reading glasses every time you try to look at something close in the headset.
