Will nearsighted people need lenses?

[SegNerd]

My understanding is that the screens on the Vision Pro will essentially attempt to emulate/recreate the world as you would see it without the headset. This creates a paradox for me: The thing you are looking at is a few cm from your face, but it is simulating being far away.

Suppose you are nearsighted, but you can see clearly at (whatever the distance to the screens is). Will you be able to see near and far without the adaptive lenses?

I don't know where they set the focal length, but I'm guessing the lenses in the unit set the natural focal length to some intermediate distance. The screen distance is uncomfortably close, even for the nearsighted. If you're nearsighted, that focal distance may be too far, so you'd need corrective lenses to correct for the lenses embedded in the unit...

Easier to add an extra lens for people who need it than make every base unit tailored for individual users.

Nobody can see clearly at 3cm, the approximate distance between the screen and your eyes.
And the focus distance of the display with the built in lenses will be at least 75 cm, and likely in the 1.5m to 2.0 range, so unless your prescription is very minor, like -0.5, you’ll need the additional lenses.

If you normally use something like bifocals/progressive lenses, you’ll only need single-vision lenses, because everything is at approximately the same focus distance.

They are sitting at a distance of where your glasses are and you are effectively looking through them in the same way to a focal point of somewhere in the range of 1.3 meters to 2 meters depending on how it is designed. It will be the same as looking at objects at that distance. Corrective lenses will need to be designed on what you are looking at 1.3 to 2 meters away."

If you get reading glasses for reading and you hold your book at arms length, and your monitor is 12" to 14" (30 to 36cm) and your monitor is 60 to 80cm - you would be best advised to get two sets of reading glasses as they are different focal points.

Ah, but there will be lenses between your eyes and the screens. These are needed to allow people to see (there is absolutely no way anyone can focus on screens that close without lenses -- try holding your finger a couple of inches away from your eyes and try to clearly focus on it).

I'm guessing here, but I'll guess the screens will be adjusted for minimal eyestrain (focal distance probably set to infinity) and 20:20 vision. The lenses will make that happen (no one can focus at that close range otherwise). This will be fine for people who have perfect vision or wear contacts (I'm also guessing this might be fine for people who are farsighted) For anyone who needs to wear glasses (nearsighted?), additional customized Zeiss lens inserts will be available as mentioned in the keynote.
