Follow up poor vision with an eye examination and cycloplegic refraction when indicated

The source estimates tens to hundreds of RMB for examination and glasses in China. Dilating drops can cause light sensitivity and blurred near vision for hours to a day or two, depending on the drug; follow the clinic's instructions.

China's Ten Key Facts explains that cycloplegic drops temporarily relax the ciliary focusing muscle before medical refraction. It calls this the gold standard for diagnosing myopia and states that appropriately used drops do not damage healthy eyes, although temporary light sensitivity and blurred near vision can occur and resolve afterward. Confirmed myopia should receive timely evidence-based management and correction with suitable glasses or other indicated methods. The document says appropriate glasses correct blurred vision and can support myopia management. For children whose corrected vision is normal, it recommends review every three to six months in preschool and primary school and every six to twelve months in junior or senior secondary school, with prescription changes according to findings. It also recommends regular refractive screening at ages 1–3, 4–6, and from age seven to monitor hyperopic reserve. The national guidance was issued in July 2023.

Evidence is B because this entry draws on official public guidance rather than an original numerical trial. The source describes suitable glasses as delaying progression; the type of optical treatment matters, so do not assume every ordinary pair has the same myopia-control effect. High myopia can involve retinal complications, making follow-up more than a prescription update. A school finding of poor vision is a screening result that still requires a complete eye assessment; see entry 7.
