So for those of you who already have Rifts, I think you're starting to realize that there is a lot that can be done by messing around with the eyecups.

After reading about foisi's fresnel triumphs, I thought I'd try out the fresnel route. I made the
USC eyecup and glued two of
these fresnel lenses together and got optics that are very close to the Rift's eye cups. Make sure to print the cup
without a raft, otherwise it will be really difficult to slide into the Rift assembly.
Differences compared to the vanilla Eyecups:
- Brought a lot more pixels into the FoV
- Significantly lessened the screen-door effect
- Made the image slightly cloudier (but it's uniform so it's okay)
- Surprisingly well focused
- Warps the image a lot more around the far edges.
I'm really happy with how much more fidelity I can get out of the screen with a new eyecup that only costs me ~$5 in raw materials. It also makes me think that there is a whole world of upgrades that can be made to the rift with just the addition of a few eyecups. The extra Screen FoV is really impressive. I can see all the borders in TF2, so I'll have to recalibrate it for that. I'm printing out another eyecup as I type this post, so I can get the full experience.
I hope more people try making custom lenses! It's exciting!
