|
 |
An uncle of mine is losing eyesight at a rapid pace needing monthly injections to restore partialeyesight in his one good eye. Is VR an option to make a desktop/movies more visible/enjoyable, or all of these headsets have these silly fisheyes blurry shit to them, nothing really enjoyable to just watch a movie/tv on ?

Well it could, but I’m not sure. If you really enlarge the desktop in your VR space you‘ll have difficulties seeing the whole screen at once, but if you make it smaller it becomes difficult to read since the resolutions are still small and it becomes blurry. I guess the HP Reverb would be the best choice to test this.
Watching movies is doable, no fisheye issues, you watch Movies on really big VR screens. Its pretty cool actually, but there is room for improvement.

I wouldn't say blurry fisheye is the problem, its the resolution like @couleur said.
Even on the index, desktop itself is hard to use.
Get it far enough away to see it all comfortably, and its hard to read the icon text. Close enough to be usable and its annoying to have to look around to do things.
Hard to explain without experiencing it. It's like the resolution is too low AND too high at the same time. Like trying to read the tiny letters on an eye chart.
There is so many pixels at that resolution the text is tiny, and its so tiny its pixel..y (not really pixelly..don't know a word for it). Don't know how to describe it. Tiny eye chart text is only vague comparison I can think of since it doesn't get pixelly as the reason you cant read it, its just 'hard' to read. No monitor analog I can make sense with, the sense of depth and distance is different.
The text is the same size as on a monitor, but it 'feels' like your trying to read it from 4-5 feet away even though scale wise the text is proportionally equal height/width.
Only obtuse explanation of the feeling I can equate it to in my experience is like when you stare at a chain link fence and its gets crossed and you have to squint and force your eyes to 'fix' it. Not the same action, but that same eye vertigo feeling at times when trying to suss out small desktop text. Like your brain going "its not that far away" and your eyes going "what? yes it is, look at it!".

thanks for feedback, what happens though when u only have one good eye ? isnt it designed to make the brain mix the two seperate images together?
someone wants to try and close one eye on his headset and share what that looks like for a slower movie and what set u got ?
sad fact of the day, his injections are like 800 euro a pop,, each month, no money, no eyesight ... healthcare is a bitch that keeps u hostage untill u die. Imagine the costs in usa ... and not a healthcare oriented country (to which he travels back every month accross the border to get em ... )

It doesn’t work like that. Your brain basically does the same thing it does normally. Meaning if one image is blurry and the other is not its still going to be messy.

You need 2 eyes to get the 3D effect.

The lenses have set focal length. I am shortsighted (about -1,5 in both eyes) and:
Dk1, dk2 both had infinite focal length fistance. Meaning the screen was just as blurry like if I was watching something far away or cinema screen from last seat.
In rift cv1, they improved the distance to about 2 meters... meaning I've seen the screen as detailed as a board 2 meters away... so still not good.
But rift S is amazing. They reduced the Focal to below 1 meter. Maybe even 70cm. It's the first vr headset where I do not need to wear correction lenses or glasses and everything is in right sharpness
