As winter vacation approaches, many parents have put their children's vision protection on the agenda. However, when faced with issues such as children's vision decline and optometry, many parents fall into misconceptions, especially when it comes to dilated pupil optometry. Ophthalmologists from Hainan Provincial People's Hospital will provide you with a one-time solution to the eye problems faced by teenagers. When it comes to mydriatic refraction, parents' resistance is very common: mydriatic refraction can make the eyes afraid of light and unable to see clearly, will it harm vision? This is actually a common misconception about mydriatic refraction. Ophthalmologists explain that the eye adjustment ability of teenagers is like a constantly tense camera. When they look up close for a long time, the ciliary muscle will continue to contract and spasm, which can easily lead to "pseudo myopia". Direct optometry can cause degree deviation. The core function of mydriatic refraction is to use professional drugs to completely relax the ciliary muscle, eliminate false myopia interference, obtain accurate refractive power, and provide scientific basis for lens fitting or intervention. It is worth emphasizing that mydriatic refraction itself does not harm the eyes. The fear of light and blurred vision that parents worry about are temporary physiological phenomena that usually recover on their own within 4-6 hours, and the specific duration varies from person to person. Refusing to dilate pupils may lead to inaccurate refraction, and the glasses provided may not only fail to correct vision, but also increase the burden on the eyes, causing myopia to rapidly deepen. The following types of children, especially those who need to undergo dilated pupil optometry: Children and adolescents who undergo visual acuity optometry for the first time are prone to developing pseudomyopia due to excessive accommodation, and the true degree needs to be determined through dilated pupils; For children suspected of having pseudomyopia, dilated pupils are a key means of distinguishing between true and false myopia; Children with unstable refractive power and rapid changes in vision in the short term require precise optometry to adjust intervention plans; For children with strabismus and amblyopia, dilated pupil optometry can provide important reference for treatment; Children with high hyperopia or astigmatism need to clarify their correction needs through dilated pupils; When clinical symptoms are inconsistent with the results of ordinary small pupil optometry, or when there are doubts about the optometry results, it is also necessary to review through dilated pupils; For children with abnormal corrected vision that cannot be explained by other eye diseases, dilated pupils can help identify the root cause of the problem. Doctors remind children that if they experience vision loss, dry eyes, soreness, and photophobia, they must seek medical examination in a timely manner. Do not purchase eye drops to relieve symptoms or randomly pair glasses. Winter vacation is the golden period for children's vision maintenance. In addition to regular optometry examinations, parents also need to guide their children to develop good eye habits: control the use time of electronic products, and look far for 10 minutes every 40 minutes of eye use; Maintain correct reading and writing posture and ensure sufficient lighting; Engage in outdoor activities for at least 2 hours every day to fully relax your eyes.
