Recently, an 8-year-old boy was accidentally shot straight into his right eye by a laser while playing with his friends. According to his statement, he just felt that his eyes were going dark and his vision was blurry, so he did not inform his parents. Until 3 months later, the school organizes a physical examination.Only to discover that the vision of his right eye plummeted to 0.4.
After a detailed examination of his eyes by a doctor,There are obvious burn marks in the macular area of his fundus, pigmentation is disordered, accompanied by yellowish-white changes, and the photoreceptor cells have been destroyed.
The deputy director of the hospital said: "The strong light energy emitted by the laser pen is highly concentrated. When it directly enters the eye, it will cause irreversible damage to the macular area of the eye in just a few seconds."
Unfortunately, even if his vision improved after treatment, his vision could not be fully corrected to normal levels. Doctors particularly remind parents and school teachers that laser pointers are not toys. If there is a laser pointer at home or in the classroom, it should be stored out of the reach of children.
When consumers purchase laser pointers for teaching or office use, they should carefully check the laser specification information of the product.It is best to purchase products with laser radiation categories of 3R and below (laser power not greater than 5mW) to ensure safe use.
