Vision Pro Viewing Focal Distance

Alrescha,

Yeh... It didn't make any sense to me either!

I confirmed your point by taking out my lens inserts and put on my contacts (with a distance Rx), then repeated the AVP setup. The passthrough looked as blurry as with using the optical inserts, so it is definitely not related to the ADD. The internally generated video was slightly more blurred because my eyes couldn't focus as well without the ADD correction. I'm sure this blurriness would become worse if I wore the AVP (with contacts) for more than 5-10 minutes (due to eye fatigue). I can use the AVP for several hours without eye fatigue using my lens inserts. This was a major concern for me since your eyes are focusing on a screen that is ~1" from your eyeball... I'm very impressed how well it works. Not sure how that works, but assume the internal (permanent) lens place the apparent focal point a couple feet in front of you.

General comment... The AVP is quite expensive and it may never catch on unless they get price between $1-2000, but I don't feel the least bit "ripped off." The technology is crazy! You're getting a full-blown computer, two 4K displays, optics, multiple cameras... not to mention the billions of $ spent on development. Version 3 will be amazing if it survives that long!

Right I think for older folks like me that have progressive glasses we usually have a pretty strong distance vision for driving and the ADD allows us to see closer things like the car dash etc or reading. Personally I just lift my glasses up to read my phone :)

So for us if we had our full distance prescription it would not be good. So like you with contacts (mine are 0.25 less than my distance glasses) it’s worse than with the lenses I got. But personally I would like than they took away to compensate for the ADD and it drives me nuts that nobody will actually tell me what it really is.

I am gonna head to my eye doctor to have her measure the inserts and then make me a new VR prescription and have Apple make that. Probably 0.25 less than whatever Apple actually made me.

Alancito, Great info!

This explains why my +1.75 ADD lens is indistinguishable from my +1.25 ADD lens (referring to the 6' focal distance). There is no way they actually use those values for the inserts... probably a small fraction (e.g. +0.6 vs +0.4 as a guess). This difference would be negligible IRL.

Well the big question we all have is what exactly is the focal distance so what prescription would be best? Its suggested in this thread that the focal length is somewhere from 4 to 6 feet. For MOST people, that is likely perfectly good with their normal distance vision glasses. However for me my distance vision glasses are just a tiny bit too strong for 4.5 feet, decent at 6 feet but still slightly strong. That is why I feel the adjustment for the ADD in my prescription is not what I really needed. My distance is -2.00, my distance contacts are -1.75 and my computer glasses are -0.75. I am pretty certain that for me around -1.00 to -1.25 would be perfect for that 4.5 to 6 foot range.

But good luck getting Apple to make that out of the box. Hence my plan to try to get a prescription sorted out for the perfect vision @ 4.5 to 6 feet then I can get them to make my lenses to that strength.

@david that is a really good point and I must have missed that about reading distance ADD. I don’t have a prescription with a 2.00 ADD because I have never needed it and with that much it’s too much for reading the dash in the car. But yeah maybe that is what I need to do is to get that prescription updated as I did have that before as it was what they did for my first set of progressives.

Either way I have to back to my eye doctor :)

Ok went to the eye doctor and got written a single non progressive prescription just for the Vision Pro so will see how that works out. I also had her measure the lenses and they did exactly what I suspected and only dropped the prescription down by 0.25 as I don’t have a full reading glass ADD for my progressive lenses. So they took it from -2.0 to -1.75 which is exactly what my contacts are and those are too strong for the Vision Pro also.

Based on my experience with the Quest 3 I went for something in the middle so we are trying -1.25 which I think will be perfect. I will let you know when I get them.

I suspect for those who have a full ADD to get to reading distance on a phone (for me that would be a full 2.00 ADD), they would likely reduce it down maybe another 0.25 to 0.5 and it would likely be perfect.

What is so annoying is that when I called and spoke to ZEISS about it, they had no clue how much my lenses were actually adjusted down. Even HonsVR sends you a note with the exact prescription you have in the lenses when you get them.

My original prescription was -2.25/-0.75 (without listing any ADD, since I do not use reading glasses). After I asked to add ADD, they added +2.25/+2.25. I guess, I will order and see :) Probably ordering without ADD would be very wrong, as I need full adjustment to see well at reading distance.

Let Apple know here:

The pass through cameras being blurred was the first thing I noticed during the demo.

For my far off stuff looks fine in pass through, other than just the general blurriness due to the lack of pixels really.

Yes but I know that the ones I got are too strong, so whatever they used to adjust it down is not enough.
