Introduction
In general, whether a child with 50 degrees of myopia needs to wear glasses depends on the impact on vision and the specific visual demands. If uncorrected vision is poor and affects seeing the blackboard in class or performing daily activities, then wearing glasses is necessary. If uncorrected vision is still adequate and does not interfere with studying or daily life, wearing glasses may not be required temporarily. It is also important to control the time children spend using electronic devices, with each session not exceeding 20 minutes.
Generally, whether a child with 50 degrees of myopia needs to wear glasses depends on the impact on vision and the visual scenarios involved. If unaided vision is poor and affects seeing the blackboard in class or daily activities, glasses should be worn; if unaided vision is still acceptable and does not interfere with studying or daily life, wearing glasses may not be necessary at this time. A detailed analysis follows:
Not wearing glasses is usually the case when the unaided vision remains at 0.8 or above despite 50 degrees of myopia, and the child can see distant objects clearly, read the blackboard in class without difficulty, and daily activities are unaffected. In such cases, immediate wearing of glasses is unnecessary. Regular monitoring of visual changes can help observe whether myopia progresses.
Circumstances requiring glasses include unaided vision below 0.6, blurred distance vision that affects classroom learning or outdoor activities, or the presence of不良 eye habits such as squinting or tilting the head to see, which may worsen myopia over time. In such cases, appropriate corrective glasses should be worn under a doctor's guidance to help the child see clearly and avoid visual fatigue.
Daily attention should be given to controlling children's screen time on electronic devices, not exceeding 20 minutes at a time and no more than one hour in total per day. Ensure at least two hours of outdoor activity daily to allow the eyes sufficient exposure to natural light. Maintain proper posture while reading or writing, keeping a distance of about 33 cm between the eyes and the book. Ensure adequate and soft lighting to prevent worsening of myopia.
