iPhone已经能够识别你何时在看它。因此，它们可以自动与你的眼镜进行通信，指示眼镜进入iPhone聚焦模式。这将使用你的处方，但会根据手机使用进行调整。未来，Mac也可能能够做类似的事情，这样你的眼镜就可以使用根据电脑使用调整的处方。因此，不再需要通过观察眼睛对齐来判断距离，这在某些眼睛对齐有问题的人身上可能会存在困难，而是可以根据设备反馈自动切换聚焦模式。

iPhones can already tell when you are looking at them.So they could automatically communicate with your glasses to tell them to go into iPhone focus mode. This would use your prescription but adjusted for phone usage.And maybe in the future, Macs would be able to do something similar so your glasses would use your prescription adjusted for computer usage.So instead of trying to determine distance by looking at eye alignment, which is problematic in some people with eye alignment issues, you just automatically switch between focus modes based on device feedback.

问HN：为什么不设计一种自动“聚焦模式”的眼镜，而不是自动对焦眼镜呢？
