Over the past month, the United States Patent and Trademark Office has published five Apple patents related to smart glasses. This demonstrates the seriousness of the project. Recently, the USPTO published another Apple patent related to smart glasses; a simple invention that will provide a special function for eyewear devices.


Apple's patent application covers devices, systems, and methods for controlling the visual light transmission properties of a first device viewing portion (e.g., glass) during an image capture event, wherein the image of the first device is captured by a second device.

In one embodiment, the lens portion of the first device can quickly transition from a first state to a second state (e.g., brighter or darker) for camera exposure. When taking photos or videos outdoors, the dark appearance of the first device portion may be converted to a light appearance.

Apple's patent drawings make it easy to understand. When taking a picture using the iPhone flash, smart glasses used as sunglasses will expose the user's eyes like clear glasses.


Apple specifically notes that, in one example, the second device triggers the first device to convert the lens portion to a more transmissive/brighter (e.g., clear) state so that the portion remains clear during image exposure, and then converts back to a darker (e.g., less clear) state. Figure 3 shows an example of controlling visual light transmission during an image capture event (camera shot).

In this example, during a first time period #310, user #25 wears the first device #10 (smart glasses) in a bright environment, and portion #15a-b (e.g., electrochromic material) is in a relatively shaded first state (e.g., dark). For example, portion #15a-b of the smart glasses may be a lens or other obscured visible portion to reduce the amount of light visible through user eyes #45a-b, such as acting as sunglasses.

In a second time period #320, an image capture event (camera shot) is initiated on the second device #20 (camera), which sends a message to the first device (smart glasses) to trigger the lens portion (lens #15a-b) to remain clear or change to clear during the image capture event (camera shot).
