After days of fighting crowds and trudging through miles of IFA's chaotic show floor, I just needed a break. I found my oasis in Aurai's water-powered eye massager. It's exactly what it sounds like: A small $239 headset that rubs your eyes with pulsating water jets. And on top of that, it can also alternate between warming and cooling modes. It's something Aurai has been working on for years, following a lengthy crowdfunding campaign. Now, the company is also gearing up for a more portable model, the Rio, which it plans to release in the first quarter of 2019 for between $150 and $175.
