Question for glasses wearers

Samsara

This may or may not be helpful, but I will tell you how I handled glasses and my Oculus CV1.

I've read that the Oculus focus at about 5 feet. This seems about right to me. I'm near sighted and my computer glasses which are tuned to about 5 feet work very well in VR. While they make my vision clear, they are a pain to wear so I got some disposable contact lenses. I have some optical insurance coverage so my cost was about $100 which gave me plenty of lenses to last quite a while.

If this is an option, I would recommend it.

You will likely not need glasses at all in VR. I'm slightly far-sighted as well (I use +2.5 for reading glasses and computer work on a monitor, but see clearly over about 6 feet from me out to infinity.) I don't need glasses in the Rift at all. Its a welcome relief!

Just wanted to second this. I have to wear +2.0 reading glasses all the time normally (i.e. I can't read text or play Elite on the monitor without them) but in the Oculus I can read perfectly without them. In fact, if I use something like Big Screen VR to display my desktop in the Oculus I can happily read facebook or this forum for example on a virtual desktop screen without any problem at all (without my glasses).

My wife on the other hand (who's short sighted - i.e. can use the computer without glasses but can't see long distance and needs glasses at the cinema for example) does have to wear her glasses in the Oculus. It's a bit of a faff to get the headset on and off again but once she's settled it's fine apparently.

Ah, I'm both Alec :) For watching TV etc., yes - but for close work (tablet etc.) I have to take the bins off. I (wrongly) assumed that I'd be fine without glasses, but one day I jammed the HMD over my (rectangular lensed glasses, and not very comfortable) told me straight away than yes - I can see in the Rift better with 'em on - damn!

If you get the vr labs lenses, can you let us know how they are? There was one post about some past issues, that may (or may not) are now resolved...

Thanks and good luck

I bought the VR-Lens Lab lenses, had them a couple of weeks now. Very happy with them. I have varifocal glasses, so I contacted VR-Lens Lab to ask them which prescription to order. They told me to order my distance prescription. They work great for me.

I wasn't enjoying wearing the rift over my glasses, quite uncomfortable, I also tried 3 different contact lens prescriptions and I just couldn't get on with them.
VR-Lens Lab was the solution for me. Took just under 2 weeks to delivery in the UK.

Not entirely true. If you are nearsighted (short-sighted) then you should not need glasses. I don't wear them on my Vive and have no issues. YMMV and my Vive can allow for glasses with adjustment. Not sure about the Rift as I do not own one, but if nearsighted try it without.

^^^ this

I absolutely need glassed to read, even to watch TV these days, but don't need them at all in the Oculus.

I need glasses to use my computer screen, my phone and for reading.

I don't need them in the Vive.

It is a bit confusing as to what vision conditions require glasses for the Rift. I contacted their support to find out what the focal distance is, so I could understand if I needed to use computer glasses, or my distance glasses. Unfortunately they said they couldn't provide that info as it hasn't been released publically. I find that a bit strange.

I saw in this thread the VR labs said to use the distance prescription to one of their customers. In my case, I don't need glasses for reading, but do need them for TV/driving, and a lesser prescription for computer work. I also recall reading blog on Oculus' site (in a development section) that seemed to indicate a focal distance of around 6'.

It seems odd there isn't better information out there about all this...

Here's what I got from Oculus support:

"At this time the focal length of the Rift has not been released publicly. All the information that has been released in regards to the Oculus Rift hardware can be found here

Via Reddit (link): "If you have a DSLR camera you can aim it inside the lenses, let it focus and then see what focal length your dslr lens says."

Well, I tried this method for you, with fairly useless results. I have a Vive, not a Rift. First problem is that my usual Nikkor G lenses don't have a focal distance scale. So I mount an old 50mm E series manual lens and eyeball the focus while poking the lens inside the Vive, and the lens reads 0.8m when the individual pixels are in sharp focus, and when using a 18-200 zoom when zoomed in to get enough magnification, 1.0m, which makes sense as the lens is physically a lot longer. Now obviously the focal plane of the camera is a little further back than where the back of my eyeball would be when in use, but this should be the right ballpark.

FWIW I have the VR Lens Lab lenses in normally to correct for shortsightedness and they are good. I would go with your distance prescription - the VR Lens Lab guys are opticians by trade and have sold a lot of these.

I think there would be issues when people are very long-sighted, or have strong astigmatism. And shortsighted people still need to use glasses in VR, as the apparent focal length is set for infinity in the Rift CV1 and Vive.

Incidentally, the Rift lenses do have adjustment for focus - the lenses are designed with a slight wedge shape so that you can position them up or down slightly within the 'central sweet spot' to change focus.
I haven't needed to adjust this though - I look straight out through the sweet spot.

This holds true for me there is a spot I can hit adjusting the mask up and down that is pretty good.

Thanks for that, I'll get in touch with them.

For the Rift it seems it's around 1m50 and that match with glasses I'm using to drive. My computer glasses meant to be sharp between 50 and 80cm make Rift blurry. I also have progressive glasses, glasses to see near at bottom and far straight and the 1m50 seems matching too with the zone I use to drive. I really dream about not using my glasses, even if now it's far better after I mod the faceplate. You feel more "free" without them, and less heat, fog, etc. I'll jump to VR Lens or equivalent one of those days ;)

Just a quick note, having received my VR-Labs lenses (prescription lenses, went for the more expensive RABS ones, no 'blueguard' stuff) - fantastic, no more glasses-wearing. All text is now as Sweet As. ED is now my number 1 game. Again.

I'm shortsighted and have glasses I use for working on my computer, and others for driving, watching tv etc. I don't need any for reading and that's why I thought I wouldn't need glasses since the rift lenses are so close to my eyes.

Anyway, I'm going to try out both pairs (computer glasses and driving glasses) to see what if any difference it makes.

Anyone else have experience and/or advice on this?

Here's a link to an article on this if anyone is interested: https://hollybrockwell.com/2015/03/13/glasses-shortsightedness-virtual-reality/

On the continuing quest to get the sharpest/clearest experience in VR...:D

This has probably been stated before but I'll chime in anyway.

The lenses in the Rift focus to infinity, so if you need glasses, you should use them with the Rift. I just use my regular old eyeglasses for nearsightedness.

I pray for the day that VR headsets have focus knobs.

If these actually work, it just might change my life for the better.

I'm pretty shortsighted (-5/-6) and were using my glasses (which are off by 1dpt against the new ones) in the Vive, it was a little bit uncomfotable, but with glasses which are not so wide it's pretty OK. My new glasses are wider and are pretty uncomfortable under the vive so I got contact lenses (one-day-lenses), which is the best under VR-HMDs. As I'm sometimes going to only play an hour or two in the evening I also got some Vr-Lenses and it's pretty neat (For an hour I'm to lazy to put contacts on :D - I'm lazy ^^).

You should know that you will most likley experience a little pillow disortion with the lenses, it's pretty much the same as with glasses, but as you normally got pretty adopted to your glasses (so your brain corrects the disortion) you will experience them with the lenses. It's the same as with new glasses before you got adopted to them. The disortion is not big but noticeable (but you will get used to it after a while).

So for best experience use contacts. :) - For me VR-Lenses has one downside, when I hop in and out VR I need to put on/off my glasses, which could be really annoying if you just want to look something in the net for a second, but it's ok for short playtime (1-2hours). For long ones on the weekend I use contacts or if I run out of them because I forgot to buy new ones :D I use my old VR-size-compatible glasses. :D

This seems to be a fair assessment of the 2nd gen VR Lens Lab Rift lenses:
https://www.youtube.com/watch?v=xvDyMIY2tAE


They notified me when their 2nd gen lenses became available, but I never ordered for the following reasons:
-concern about fit and scratching my Rift fresnels (as the nubs that fit under the faceplate are plastic I am concerned that constant manipulation will weaken them and the lenses will become more loose over time)
- demoing and sharing with friends and constantly putting in and taking out the VR lenses
-Rift off, glasses on, swap that the vid mentions is a pain for me, where as, with contacts I can lift and peek to type (eg. galaxy map in Ed or a game like Assetto Corsa where the menus are non-vr )
-added weight
-still concerned that my "high prescription" will result in some barrel distortion. YMMV

I will say that when I had issues with the 1st gen VRLL lenses their support was "Top Notch". They communicated promptly and when they couldn't resolve my issues they refunded my money as soon as I gave them return shipping info. If this is still their policy, I see no reason those who need glasses shouldn't give VRLL a go. YMMV
