These alarm glasses aren't just stylish, they also keep the user safe while they wear them. There are many different ways that a deaf person can keep themselves safe when they're out on the town, but these alarm glasses use another one of the senses to keep them alert.
The main purpose of the glasses is to let the user know of incoming danger around them as they walk around. Whenever danger approaches -- such as a car for example -- the glasses will sound an alarm, allowing them to respond faster. Whenever there's a really loud noise, like shouting, the glasses will alert the user.
Keeping yourself safe when you're on the road is more difficult when you're hearing impaired, so these alarm glasses will certainly help.
