Fresnel Lenses Alternatives?

I love my Vive vr, but absolutely hate the fresnel lenses as the ridges pick up any glow and create a lense flare effect.

Has anyone tried any optional lenses?

does the index have the same fresnel lenses? are the index's lenses compatible with the vive (I use glasses and have prescription inserts, wondering if they would fit the index)?

Unfortunately glare/godrays is one of the known downsides of Index. So far I think only Oculus has managed to eliminate most of it, though I am looking forward to the HP Reverb G2. In a QA they did with MRTV they promised to reduce the glare. We will see soon enough they were successful or not.

I guess this is a cost and compactness/optical packaging thing, as I come from a background where we do not skimp out on optics, because otherwise shit breaks. I can have custom solutions made that practically nullifies wavefront distortion across the visible range while expanding an objective, so I don't see why it is not possible here whilst avoiding Fresnel approach..

That is disappointing but good to know, been on the fence about the Index and that puts a pin in it until a better solution comes out. I'm 95% certain that my motion sickness in VR is coming from the godrays distracting my eyes.

Very unlikely.

The most likely causes are running too high of settings and dropping down lower than the refresh rate of the headset, this can happen a lot easier than people think. Especially if you are running SS.

Or that you haven't fully got your VR legs and you continue to play even after you start feeling nauseous.

Unlikely. I've had vr since the oculus DK2, went from that straight to the vive on launch, I make sure to keep frames up over graphics, though I've never tested fps.

I find the fresnel lines visible and the godrays cause my eyes to flicker and focus on them rather than the game. It was in a hour long session of elite last night that i finally pulled my HMD out for that I really noticed the effect the godrays where having on my experience.

edit: I do push past nausea a little bit, trying to extend my vr legs as you say. weird part is in the DK2 I could play for hours without issue, used Vorpx and rocked payday 2 for days was a blast.

As I said, it's highly unlikely that the Godrays are giving you VR sickness. If your symptoms were headaches or sore eyes or feeling dizzy I might say it was the Godrays.

A Game like Elite Dangerous is the kind of game most likely to cause VR sickness. So first you should try turning off all SS and lowering the settings and see if you still get motion sickness.

If you are still feeling motion sickness even with lower settings you will have to go through the process of retraining your brain again. How you do that is that you stop playing and take off the headset the second you feel VR sickness coming on. Stay away from VR then for at least 15 minutes. If you have fairly good VR legs it won't take long at all to get to a stage where you aren't feeling sick at all.

And if all that fails, try eating some ginger before playing.

Good optics do not come cheap, I remember when we purchased a 1.5KW CO2 industrial laser off a textile floor facility to do ablation resaerch for 100 grand, the optics alone cost more than the laser. The laser looked like a industrial clothes dryer about 12 feet tall, scared the hell out of the Univ safety peeps. With no optics in beam line it would punch through a 6 inch block of bulletproof Polycarbonate in under a sec and the IR beam is invisible to the eye.

dizzy is a better description, its not quite nausea, more like eye strain when my glasses prescription is off.

I'm going to order those lenses above and see what happens, will report back for those that may want to rid themselves of fresnel lines.

Do report back, I hope they work out for you.

Wasn't there a mod for the Vive Pro that replaced the Fresnel lenses with ones from the Gear VR. Maybe that might work on the Vive?
