Have you paid attention like an accountant or an inveterate gamer is getting a glazed look after a day of stupor in a monitor? It’s harmful to sit in front of a computer for days, and if you don’t even blink, you can generally remain blind after a few years.
The Japanese are very worried about vision impairment, and therefore have made special glasses that track how often a person blinks. If the sensor notices that the person has not blinked for a long time, the glass of the glasses becomes opaque. Return a normal review can only make a movement for centuries. ')
The glasses work 8 hours on battery or unlimited from USB. Sold for 150 dollars.
