Recently, I often realize that because of modern technology, people lose their sight. In advertisements I see: eye drops to improve the eyes. In fact, no drops here will help. Vision will progress and deteriorate each time. Maybe someone will improve, but in rare cases. In my opinion, only an operation will help here. And the people who created such drops earn in this way, luring people who so hope for it. in my opinion, it would be better to come up with something useful, for example, a cure for cancer, than a new iPhone, which costs a lot of money. People are getting stupid because of this, also these gadgets that create and affect vision more. I want the world to be smarter and understand simple things in this life.
