The "EYEs" references the fact that the smartphone features dual front-facing "selfie" cameras. In this case, there are two 5MP sensors (f/2.2) that allow you to take selfies in portrait mode (which the ever-popular bokeh effect). This should provide results similar to what you would find on the rear cameras of flagship smartphones.
The dual cameras are also used for face unlock, and have the ability to decipher whether they are looking at a real person or an image/video. There's no word yet on if the cameras can be tricked by using a 3D mask -- as is possible with the iPhone X -- but we'd confidently say that the answer is probably "yes". It should also be noted that HTC only allows you to use the feature to unlock your devices, and it isn't considered secure enough to authorize payments.
As for the rear camera, it's a 12MP shooter (f/1.7) that uses HTC's UltraPixel technology. Below the camera you'll find a fingerprint sensor for unlocking the smartphone and authorizing payments (among other things).
Powering the smartphone is a Qualcomm Snapdragon 652 processor with 4GB of RAM, 64GB of storage, and a 6-inch display (2160x1080). Also onboard is a rather large 3,950 mAh battery, which should allow for some rather long runtimes. And you'll be happy to know that the U11 EYEs will come straight from the factory with Android Oreo installed.
The HTC U11 EYEs will go on sale this week in Hong Kong priced at around $500. There is no word on when it will arrive stateside, or how it might be priced with it arrives.
