展示HN：创建了一款macOS应用，帮助你保持与屏幕的距离
大家好，
如果你和我一样，可能会发现自己一天（甚至晚上）有很大一部分时间都在电脑前。我常常发现，当我全神贯注时，坐姿越来越差，脸离屏幕越来越近。经过一整天的工作，当我终于离开电脑时，我的眼睛很难聚焦远处的事物。这已经成为一个足够大的问题，以至于我决定开发一个应用程序，帮助我保持脸与屏幕之间的距离。
我本可以选择一个简单的带有计时器的通知，但就像所有的提醒通知一样，它们很快就会变成噪音，我最终会选择忽略它。我需要一些能够主动迫使我后退的东西，这就是FarSight的作用。
它利用你的摄像头来测量你与屏幕的距离，如果检测到你在一定时间内靠得太近，就会模糊整个屏幕。我设计它的方式是不会让人感到极其烦人和干扰（例如，每次你越过界限时都会模糊屏幕），而只是足够恼人以便于帮助。我自从创建以来每天都在使用它，它确实帮助我缓解了眼睛疲劳、双重视力，令人惊讶的是，也改善了我的坐姿。
我不确定是否会一直免费，但我想先发布它以征求反馈。目前我只在MacOS上有这个应用，如果有足够的兴趣，我会投资制作Windows版本。
另外，想告诉大家的是，应用使用期间不会收集任何数据，快照仅用于计算距离，不会保存。

Hey everyone,<p>If you're anything like me, you spend a good chunk of your day (and night) on your computer. I often find that when I'm zoned in, my posture gets worse and worse and my face ends up being really close to the screen. And over a course of a workday, when I finally unplug, my eyes have a hard time focusing on things that are far away. This has become a big enough problem for me that I decided to create an app to help me keep my face far enough from the screen.<p>Now, I could've gone with a simple notification with a timer built into it but, as with all reminder notification, they soon become noise for me and I end up just dismissing it. I needed something to actively force me to move back. Which is where FarSight comes in.<p>It uses your camera to gauge your distance and blurs the entire screen if it detects that you are getting close enough for a certain period of time. I made it so that it won't be extremely annoying and disruptive (e.g. blurring the screen every time you cross the line) but just enough of a nuisance to be helpful. I've been using it everyday since creating it and it's definitely helped me with eye strain, double vision, and surprisingly, my posture as well.<p>I'm not sure if I'll keep it free forever but I wanted to release it first to ask for feedback. I only have the app in MacOS so if it has enough interest, I'll invest into making Windows counterpart.<p><a href="https://apps.apple.com/us/app/farsight-restore-your-eyes/id6753566841?mt=12">https://apps.apple.com/us/app/farsight-restore-your-eyes/id6...</a><p>Also, in case anyone is wondering, no data is collected and the snapshots during the app's usage are not saved but only used to calculate the distance.
