Apple Watch Green Light

You might have noticed the green light ON in your Apple Watch. Especially found under the case of your device. Though it is not harmful, there might be instances you would like to have it switched off. Please remember, the Apple Watches come with excellent sensors and all the features of the watch are beneficial.

But what is this Green Light for?

Before we could get on to the method to switch off the Greenlight, let us understand the purpose of the light on your Apple Watch. This shall give you a fair understanding of the watch’s operational functionality.

The Green LED light that is ON under your Apple Watch is to indicate that the device is measuring your heart rate. In fact, the App present in the watch is recording the measurements. It does happen continuously as it records the heartbeat with utmost accuracy.

Is it Explicitly available in the Apple Watches for others to See?

Well, the Apple watches were manufactured with Optical sensors in-built in the system. They are present primarily to measure the heart rate. These optical sensors emit the LED light on your wrist and calculate the heart rate accurately.

You would have even noticed that the green LED light is ON even while not wearing it. Though it might be for a few seconds, the reason for the lights flashing is to indicate that the App for calculating the heart rate is still functioning. Moreover, the watches are designed to have the lights off when removed from the wrist.
