The Oculus Rift developer kit now comes with three pairs of removable eyecups, instead of a single, permanent set. The different eyecups allow you to switch the focal distance of the developer kit between three predefined settings. This means that if you’re nearsighted and your vision isn’t too bad, you may be able to use the developer kit without glasses or contacts.
Here’s how they work:
- If you have great vision (or you wear contacts), your vision inside the Rift will match your vision in real life. You’ll use eyecup set A.
- If you’re farsighted, you’ll have no vision problems in the Rift because the optics are focused at infinity (which makes your brain think it’s looking at something far away). You’ll also use set A.
- If you’re nearsighted, the additional eyecups, B and C, allow you to see inside the Rift as if you were wearing glasses. Again, this is because the lens cups change the focal distance. If you’re moderately nearsighted, you’ll use set B. If you’re very nearsighted, you’ll use set C.
“This isn’t the perfect solution: the B and C cups won’t be ideal for everyone, but we’re hoping that they help some of the nearsighted developers. If you have other eye issues like astigmatism, the additional lens cups may not be sufficient. In short, your mileage may vary.”
