【實用健康app】Best Vision Eye App|最夯免費app-綠色工廠好玩App

Staring at something too close, or for too long, causes eye strain and can also lead to blurry vision and headaches.

This is the FIRST AND ONLY app (as of April 3, 2015) that help enforce both:

1. the 20/20 Rule: It will remind you to take a break (look away at 20 feet for 20 seconds) after 20 minutes of looking at your electronic device.

Your device will vibrate after 20 seconds letting you know the break is over and that you can use your device once again.

2. Harmon’s Rule: It will notify you if you are too close to your device.

Harmon's Rule: Position your computer monitor between 20 to 26 inches (50 to 65 cm) from your eyes.

For all other near activities (such as using cell phones or tablets, reading, playing with hand-held video games, etc.), 14 to 20 inches (35 to 50 cm) is considered appropriate.

Notes:

1. This app needs a few seconds to calculate the distance between the device and your eyes. Therefore, if you place your device too close to you, it will take a few seconds before the notification “You are too close to your device” appears.

2. We do not recommend changing the Time between breaks or the Break duration. Once you change those settings, you cannot change them again without uninstalling and re-installing the app.
