Laser pointers are also called stargazers, originally used by astronomers to watch stars. However, the laser pointer has been changed to a new use in Hong Kong's six months of revisions. In the eyes of demonstrators, it can interfere with police forensics and shooting, but in the eyes of doctors, it is a dangerous weapon that can cause irreversible damage.
What is a laser? It is a very powerful beam of energy, this beam is very useful. If these powerful lasers are used improperly, for example, when they are used to scan people, and when the eye is focused on your laser, it can blind the eyes in a very short time, which can be said to be 0.1 second. And it’s blinding is irreversible, that is, there is no medicine to heal, no surgery to do, that is, if it is blinded in 0.1 second, it will be permanently blind.
As an ophthalmologist, I am always in awe of the laser. As early as 20 years ago, because of the abuse of green laser pointer in the beauty industry, the Hong Kong Laser Medicine Association was founded with the purpose of calling on relevant departments to regulate the use of lasers. Nowadays, a large number of powerful laser pointers are appearing on the street, which makes Dr. Zhou worry.
In the UK, we know that if you want to buy a powerful laser (equipment), first you want an adult, and second, you need to register and control it. What did you buy for? Where do you live? who are you? These need to be registered before you can buy them. We do not have this law in Hong Kong, so in this regard, I am here to call on the relevant authorities to do their work to protect our citizens.
