In this podcast, Dan Clark looks at safety glasses with sensors to monitor the eyes for signs of fatigue.

Opalert is available now. In a few months JINS Meme and Google Glass will be available in the US.

Dan Clark: Safety glasses that can monitor your blinking to tell when you’re tired? They’re here and more are coming. Safety glasses with drowsiness detection.

Smartglasses. Wearable technology. Turbocharged safety glasses. Whatever you call them, they could be a safety revolution. These glasses have eye-tracking software to monitor fatigue and attention levels. These could be hyper important for truck drivers (or any drivers), people operating dangerous machinery and workers with power tools.

Three manufacturers caught my attention: JINS in Japan; Australia’s Optalert and Google Glass in the United States.



○ FIRST – The Japanese eyeglass maker JINS. They’ll launch the Meme—M E M E—soon in the US. It’s wearable tech that looks just like regular glasses. The Meme is loaded with tiny sensors. On the earpieces. Around the frames. On the nose bridge. They’re everywhere. And they track blinking to gauge how you’re feeling even before you realize that you’re feeling sleepy. It monitors head movements and observes your posture.


The Meme connects to its free smartphone app wirelessly. Warnings pop up and alarms sound on your smart device. The battery life is great—16 hours of continuous use. It’s charged with a micro USB and you’ll be able to get prescription lenses. JINS is selling the Meme in Japan this fall and in the US sometime in 2016.



○ SECOND – Optalert. This is available now. These glasses look like traditional safety glasses. They protect the eyes to the ANSI Z87.1–2003 standard. You put the glasses on. A wire connects them to Optalert’s own proprietary dashboard tablet or mobile device for your wrist.

The safety glasses monitor eye blinks up to 500 times a second, sending data to the hardware. The connected hardware device gives a visual readout of drowsiness. If the wearer is really sleepy, an alarm sounds.

Optalert is converting to Bluetooth, which will do away with the cumbersome wire going from glasses to the device. And it can be outfitted with prescription lenses.



Safety_Glasses_With_Drowsiness_Detection-Creative_Safety_Supply-250x143○ THIRD: Google Glass. After being put on pause in 2014, new patents were filed in April. The Enterprise Edition of Google Glass will be out in December this year, 2015.

Now, the problem with Google Glass is it’s an extension of a smart device. It projects text or video into your field of vision, which is thoroughly unsafe for driving or operating equipment.

BUT, if you can avoid using those features, an app is in development called “Glass Fatigue Detector” which tracks blinking and head rotation to calculate drowsiness. The app will alert you when fatigue sets in. You’ll see versions for both Android and iOS devices when Google Glass hits the street, says the app creator, Dr. Jibo He, at Wichita State University.

So, if you need a high-tech set of spectacles check out the Optalert system now or the Meme by JINS and Google Glass in a few months.
