Ask HN: 与其使用自动对焦眼镜，为什么不开发自动“专注模式”眼镜？
1 分•作者: amichail•大约 1 个月前
iPhone 已经能够判断你是否在看它了。
因此，它们可以自动与你的眼镜通信，告知眼镜进入 iPhone 专注模式。这会使用你的处方，但会针对手机使用进行调整。
也许在未来，Mac 也能做类似的事情，这样你的眼镜就会使用针对电脑使用调整过的处方。
所以，与其通过观察眼睛的对准来判断距离（这对于一些有眼睛对准问题的人来说是有问题的），不如根据设备的反馈自动切换不同的专注模式。

iPhones can already tell when you are looking at them.<p>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.<p>And maybe in the future, Macs would be able to do something similar so your glasses would use your prescription adjusted for computer usage.<p>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.
