My invention is a pair of magic glasses.
This pair of glasses is very special. There is a tiny camera in the glasses. The camera can record things. When old people put on these glasses, they help them remember things. When students put them on, they help students study. We can watch the videos if we want to review lessons in classes. If the police put on these glasses, they can easily find the evidence of the crimes. They help to make crimes less.
It’s a great invention.
