Researchers predict that by the year 2050, about half of the world’s population will have myopia.
Considering the target demographic, a significant number of potential VR users suffer from myopia already. Why are there no more VR headsets with adjustable focus?
Several vendors offer replaceable lenses, or various addons to fit the glasses in, but the obvious solution used by the early cheap headsets like GearVR - adjustable distance between lenses and the display, is not being utilized for some reason.
Is it a technical problem, economical problem? Are the modern lenses somehow tuned for a specific distance?
Because they are making them to be as “one size fits all” as possible, which also reduces cost. If you need corrective lenses outside of VR, you usually have to get custom made lenses to fit your prescription or just get one/an accessory for one that lets you wear your glasses in the headset.
They could give all the attention in the world to how human eyes vary, and they still would have this issue because corrective lenses are not cheap to make, and everyone is extremely unique that they couldn’t possibly make a simple “works for everyone out of the box” device.
I don’t know how many other headsets are, but the Quest 3 has a pretty good method of adjusting both the distance of the lenses from your eyes, as well as the distance between your eyes to get perfect focus. But again, it assumes you don’t have any vision problems outside of the device.
