Myopia in Hong Kong
Since the advent of smart phones, I believe that most Hong Kong people have never left their mobile phones. At the same time, there is a crisis that is slowly approaching and everyone is not aware of it! According to the Hong Kong Ophthalmological Association in 2019 , the proportion of myopia among adults in Hong Kong is the highest in the world.
At the same time, the Time Association also conducted eye examinations for about 13,559 children, and found that the myopia rate of children aged 4 to 9 has increased from 7.7% to 44.5% , which has nearly tripled in just three years. related.
Of course, it is not that simple. According to the publication "Growing Digital: An Overview of Children's Use of Screen Media" issued by the Department of Health in 2019 , 13% of children spend an average of 3 hours or more per day in just 5 years. Going online, this habit is very likely to be the sequelae of Mommy's "electronic pacifier". If things go on like this, just like the international report cited by Dr. Yam Cheuk-sing in " Public Education Event 2019 " in 2019 , nearly half of the population will suffer from myopia by 2050 !!
Short-sighted sister, wear glasses! ?
According to the publication of the "Student Health Service" of the Department of Health, it has been pointed out that glasses can only correct vision, that is, " see clearly " , but they cannot cure myopia or even prevent the progression of myopia, so everyone should not think about it There must be no problem if you wear glasses.
Is myopia a big deal?
It is true that myopia is the most difficult to see clearly, but myopia may lead to other more serious diseases. As Dr. Yip Pei Pei, President of the Hong Kong Academy of Ophthalmology, has pointed out, deep myopia makes the eyeballs elongate, which is very large. There may be retinal breaks or even detachment, which may also lead to eye diseases such as macular degeneration, glaucoma and cataracts, and the most serious may cause blindness. So everyone prays not to ignore the health of the eyes.
