Core Viewpoint - The article discusses common misconceptions about myopia prevention and treatment in children, emphasizing the importance of accurate eye examinations and appropriate corrective measures. Group 1: Eye Examination Methods - Cycloplegic refraction is a standard method for assessing children's refractive errors, temporarily paralyzing the ciliary muscle to obtain accurate measurements [1] - Quick cycloplegia is suitable for children over 8 years old, using a combination of tropicamide eye drops, with a fast recovery time [1] - Slow cycloplegia, using 1% atropine ointment, is recommended for younger children, providing more accurate results but with a longer recovery time of about three weeks [1] Group 2: Myopia Treatment Guidelines - Children with myopia between 50-300 degrees may not need glasses if their naked eye vision is acceptable (0.8 or above) and they do not experience significant eye strain [2] - For moderate myopia (300-600 degrees) and high myopia (over 600 degrees), it is advised to wear corrective glasses all day to prevent further eye strain and elongation of the eyeball [2] Group 3: Importance of Regular Check-ups - Regular follow-ups every three months are essential after getting glasses to monitor changes in vision and eye axis length, allowing for timely adjustments in myopia management strategies [3] Group 4: Other Common Eye Conditions - Besides myopia, conditions like amblyopia, astigmatism, and strabismus are prevalent in children and require attention [4] - Amblyopia, if not treated by age 6-8, can lead to permanent vision impairment [5] - Astigmatism is often congenital and can be corrected through glasses or contact lenses [6] - Strabismus requires professional evaluation to determine the cause and severity for personalized treatment [7] Group 5: Myopia Prevention Misconceptions - Wearing glasses does not cause eye deformation; they are external aids and do not affect the eye's development [8] - Low-concentration atropine eye drops can slow myopia progression but cannot reverse it [9] - Corrective lenses should match the child's actual refractive error; under-correcting can lead to increased eye strain and worsen myopia [10] - Wearing appropriate glasses does not worsen myopia; in fact, not wearing them can accelerate its progression [11]

Group 1 - The article defines myopia levels: low myopia is classified as 50 to 300 degrees, with 50 to 100 degrees being the lower range of low myopia [1] - For individuals with a naked eye vision of 0.8 or above, it is suggested to avoid glasses temporarily if daily activities, such as viewing a blackboard, are not affected, but vision should be rechecked every three months [1] - Moderate myopia ranges from 300 to 600 degrees, while high myopia is classified as over 600 degrees [1] Group 2 - Doctors recommend that individuals with moderate to high myopia wear frame glasses throughout the day to prevent eye strain caused by blurred vision, which can lead to excessive eye axis elongation and increased myopia [1]

Core Viewpoint - The increasing use of electronic devices and poor eye care habits are leading to a rise in eye health issues such as myopia and eye fatigue across all age groups [1] Group 1: Myopia Understanding - The distinction between true myopia and pseudo-myopia is best determined through cycloplegic refraction, which involves using a cycloplegic agent to relax the eye muscles before testing [2] - True myopia persists after dilation, while pseudo-myopia may resolve or significantly decrease, indicating it is related to eye strain rather than structural changes [2] - Myopia can be corrected through optical means such as glasses or contact lenses, but it cannot be fundamentally cured as the elongation of the eyeball is irreversible [2] Group 2: Genetic Factors and Myopia - High myopia can be hereditary, particularly when caused by genetic abnormalities, which typically manifests early and at high degrees [2] - Most myopia is influenced by environmental factors, such as excessive near work, and while early onset and rapid progression can lead to severe myopia, this is not directly inherited but rather an increased susceptibility under similar conditions [2] Group 3: Eyewear and Myopia Progression - Wearing glasses does not worsen myopia; in fact, not wearing appropriate eyewear can accelerate its progression [3] - Studies indicate that adolescents wearing properly prescribed glasses experience slower myopia progression compared to those with under-corrected lenses [3] - Regular eye examinations are recommended to ensure that prescriptions remain accurate, especially for children [3] Group 4: Eye Health and Device Usage - Viewing screens in dark environments can be harmful due to increased pupil dilation and exposure to harmful blue light, which may damage the retina over time [4] - Reduced blinking while focusing on screens can lead to dry eyes and discomfort; using night mode and ambient lighting is advised to mitigate these effects [4] Group 5: Eye Fatigue Management - To alleviate eye fatigue, it is essential to control screen time, with recommendations to take breaks every 30 to 40 minutes and follow the "20-20-20" rule [4] - Maintaining appropriate lighting and screen settings can also help reduce eye strain [4] Group 6: Myopia Management - Effective myopia management focuses on early detection, intervention, and regular monitoring under professional guidance [6] - Parents are advised to avoid non-medical claims of vision recovery and seek professional evaluation if they notice a decline in their child's vision [6]
