Patient's question:
NoDoctor's answer:
Hello, the purpose of dilation is to relieve eye fatigue and allow the muscles that regulate tension to relax, so that the measured refractive power is more accurate. Dilation itself will not cause adverse effects to the patient, and the use of dilation medication must be under the guidance of a professional doctor or optometrist. However, after dilation, there may be temporary symptoms such as photophobia and blurred near vision (distance vision is unaffected and normal life can still be carried out). The time to recover varies depending on the type of dilation medication used. Tropicamide generally takes 4-6 hours to recover, atropine takes 3 days, and atropine dilation typically takes about 2-3 weeks to recover on its own.
