The researchers have already begun testing software fixes and two different types of hardware options. Since the main problem with current displays is that they make it difficult for your eyes to focus on one point due to their proximity to your face, the prototypes were designed to solve the issue. One of them uses liquid lenses that can be adjusted by squeezing a dial, while the other works like binoculars and moves the display screen back and forth. Both of them incorporate an eye-tracking technology to figure out where you're looking.
At the moment, the prototypes can only help you if you are nearsighted, farsighted or presbyopic, but it can't help you with, say, astigmatism. The researchers say this is only the beginning, though, and they're hoping their "research findings [can] guide these developments in the industry."
