Abstract: the visual stability of teenagers and children is not enough. Due to the strong eye adjustment function, the degree of optometry is easy to be judged by the children’s subjective reaction, resulting in great error., Many readers know that mydriatic optometry is necessary to match children with myopia glasses. In fact, 20% of adults also need mydriatic optometry. Lu Jinhua, an optometry expert at Sun Yat Sen ophthalmology center of Sun Yat sen University, said in an interview that this is mainly due to the sharp increase in close-up eye use by adults in recent years, especially after the emergence of smart phones and tablet computers, which leads to false myopia in some adults. If mydriatic optometry is not used, the degree of glasses is inaccurate, which further aggravates visual fatigue and forms a vicious circle., Adults with excessive eyesight also have pseudomyopia. Optometry expert LU Jinhua introduced that in the past, pseudomyopia was mostly associated with children and adolescents. Now, due to the emergence of more and more “visual fatigue” people, adults also began to have pseudomyopia., He explained that in recent years, due to the emergence of smart phones and tablets, adults’ eye habits have changed greatly from the past. Long time close reading, reading too small words, computer operation for too long, etc. will overuse the adjustment ability of the eye, which can cause visual fatigue symptoms such as eye swelling and pain, dry hair, blurred vision, heavy eyelids, and even headache, orbital pain, even nausea and vomiting. This is “visual fatigue”., The discomfort caused by visual fatigue is actually a signal from your body that your eyes need to rest. If you are still reluctant to let your eyes rest for a while, so that your eyes are in a state of fatigue for a long time and can not be relieved and adjusted, it is easy to lead to ciliary muscle spasm. The continuous contraction time of ciliary muscle is too long, so that your eyes are in a state of fatigue and myopia for a long time, and regulatory myopia, namely pseudomyopia, will occur., 20% of adults need mydriatic optometry. This kind of pseudomyopia in adults will bring difficulty to the optometry. Just as children prone to pseudomyopia need mydriatic optometry when they are wearing glasses, these adults with pseudomyopia also need mydriatic optometry in order to get accurate eyeglasses., Many readers of
know that mydriatic optometry must be accurate when children are equipped with myopia glasses. In fact, 20% of adults also need mydriatic optometry when they are equipped with glasses.

and
overuse adults also have pseudomyopia. Lu Jinhua, an optical expert of

he explained that in recent years, due to the emergence of smart phones and tablet computers, adults’ eye habits have changed greatly from the past. Long time close reading, reading too small words, long computer operation time, etc. will overuse the adjustment ability of the eye, which can cause visual fatigue symptoms such as eye swelling and pain, dry hair, blurred vision, heavy eyelids, and even headache, orbital pain, even nausea and vomiting, which is “visual fatigue”.
the discomfort caused by visual fatigue is actually a signal from your body that your eyes need to rest. If you are still reluctant to let your eyes rest for a while, so that your eyes are in a state of fatigue for a long time and can not be relieved and adjusted, it is easy to lead to ciliary muscle spasm. The continuous contraction time of ciliary muscle is too long, so that your eyes are in a state of fatigue myopia for a long time, and regulatory myopia, namely pseudomyopia, will occur.
20% of adults need mydriatic optometry.
this kind of pseudomyopia in adults will bring difficulty to the optometry. Just as children prone to pseudomyopia need mydriatic optometry when matching glasses, these adults with pseudomyopia also need mydriatic optometry to match glasses with accurate degree.
and
Lu Jinhua explained that the visual stability of teenagers and children is not enough. Due to the strong eye adjustment function, the degree of optometry is easy to be judged by the children’s temporary subjective reaction, resulting in great errors. Mydriasis is to use special eye drops to inhibit the subjective adjustment function of the eyes, so that the diopter can be checked objectively and accurately, and the degree of glasses will be accurate. The same is true for adults with pseudomyopia. If ordinary methods are used for optometry, the diopter tested is unstable and will fluctuate. After mydriasis, accurate diopter can be obtained.
he said that from clinical observation, at least 20% of adults who come to optometry need mydriatic optometry in order to obtain accurate diopter.
“visual fatigue” people especially need mydriatic optometry
many adults choose to optometry in ordinary glasses stores for convenience. If he has pseudomyopia, the diopter obtained without mydriatic refraction may be 50 to 150 degrees more than his actual diopter. In this way, the degree of glasses is far from the correct degree, which is over corrected.
and
wearing such “over corrected” glasses for a long time will make the wearer feel very uncomfortable, aggravate his visual fatigue, and then form a vicious circle. For some patients with high myopia, if they are in visual fatigue for a long time after entering adulthood, they will not only have pseudomyopia, but also aggravate their true myopia.
and
Lu Jinhua said that mydriatic optometry is a rigorous medical behavior. Mydriatic optometry is allowed only in formal medical institutions. Ordinary optical shops are not medical institutions. Mydriatic optometry is not allowed according to national laws and regulations.
whether adults need mydriatic optometry is judged by experienced optometry professionals. He reminded that if you usually have eye pain, dry hair, blurred vision, orbital pain, irritability and slow adjustment (that is, under normal circumstances, the adjustment time from seeing close to seeing far is very short, so short that you can hardly feel it, but someone with “visual fatigue” is reading a Book and suddenly looks up at the distance, there will be a problemIf you have blurred vision for two seconds before you can see clearly) and other suspected symptoms of “visual fatigue”, you might as well tell the doctor during optometry to remind him that you may need mydriatic optometry.
there are skills to alleviate visual fatigue
A. if you can surf the Internet with a computer, you don’t need a mobile phone. The words on the mobile phone are small and close to your eyes.
B. look up or turn around for 20 minutes.
C. blink more. Blinking is the natural masseur of the eye. But when we stare at the computer screen, we will forget to blink. Without blinking, our eyes are easy to dry, which will also pay more attention to fatigue.
D. gently buckle two eyes. First put the five fingers of both hands together, and then rub them hand to hand until the hearts of both hands are hot. Close your eyes slightly and gently buckle the hot palm on your eyes with a hollow palm speed. After about 3 minutes, the palm of your hand is away from your eyes, and then slowly open your eyes. Suddenly, you will have a feeling of clear eyes.
