Today, the number of myopia in my country has exceeded 600 million. According to statistics from the National Health Commission, the overall myopia rate of children and adolescents nationwide in 2018 was 53.6%, of which 81.0% were high school students and more than 90% of college students. In other words, over 90% of our college students are myopia. Eyes help us accomplish various tasks every day, perceive the novel things around us, and are our most loyal companions. Do you really know how to protect our eyes?

 

 

Knowledge 1: What makes your eyes uncomfortable?

Although the occurrence of myopia is mainly caused by environmental factors and genetic factors, staying up late to stay in the dark use mobile phones, look at mobile phones while walking, use your eyes for a long time, wear contact lenses for a long time, rub your eyes with your hands, abuse eye drops... .. These bad eye-using habits in modern life not only make our eyes "overwhelmed", they also cause discomfort such as soreness, dryness, swelling, and tears in the wind, aggravating myopia, and may even lead to various eye diseases.

 

 

Knowledge 2: Eyes also need sun protection?

Eyes need more "sun protection" than skin. According to experts, the eyelid is a part of the skin, and it is more fragile and more vulnerable than skin elsewhere. Therefore, if the eyelid skin is exposed to ultraviolet light for a long time, it will increase the probability of diseases such as cataracts and macular degeneration, and may even increase the incidence of skin basal cell carcinoma.

 

Good sun protection for the eyes, sun umbrellas and sun hats have a certain effect, and it is also very important to choose a suitable pair of sunglasses. Not all sunglasses have UV protection. You can choose sunglasses with UV400. Sunglasses with darker lenses have a better filterability for glare. Light colors are more suitable for cloudy days or occasions where the sun is not too strong.

 

 

Knowledge 3: Can seeing green really protect the eyes?

Many people say that green can protect eyes. So some friends changed their mobile phones and computer desktops to green. Can green really protect the eyes? Compared with red and yellow, green absorbs and reflects light more moderately, so it makes people feel more comfortable, but this does not mean that it can "protect the eyes." Looking into the distance is really good for the eyes. Objects within 33 cm, even if they are green to "glow", are not helpful to the eyes.

 

 

Knowledge 4: Can tears also protect the eyes?

When our eyes are open, the cornea and conjunctiva are exposed to the outside world, and air, light, bacteria, etc. will stimulate them. On the outside of the cornea and conjunctiva, it is the "tear film" that protects our eyes. The tear film protects the eyes from all kinds of damage, and at the same time it is full of many nutrients, which can make our eyes brighter.

 

People say that the eyes are the window of the soul, and only with a pair of bright and transparent eyes can we better appreciate the vast world and infinitely wonderful. Let's close our eyes and take a break~
