My second product is:
Laser Glasses. With this product, the wearer needs to focus his/her eyes on the physical abuser and a light will be emitted from the glasses which will cause irritation in the eyes of the abuser. This only works if the abuser is within a particular range from the defendant and the reaction lasts for few minutes which can help the defendant escape.
According to OP ,what if the harasser if wearing the same glasses ?What if the wearer focuses on his girlfriend wearing the same ? Also,there are chances of the harasser wearing a helmet right ?
You have missed the fact that the defendant is wearing glasses. And helmet? That's a rare scenario while if the abuser is wearing glasses, it won't be as power as the laser glasses.
I know that you are unhappy that your ideas have been question but this is a contest and only one person will win. I have also lost contests but there's no point arguing for it. Just have sportsman's spirit.
