The approximate time it takes for pseudomyopia to become true myopia is uncertain and varies from person to person. Pseudomyopia, if left unchecked, usually becomes true myopia within six months or less. Pseudomyopia is a special state of myopia, i.e., myopia symptoms that usually manifest as unclear vision at a distance and normal myopia symptoms at a near distance, but vision returns to normal or manifests as hyperopia after rest or medication for astigmatism. This condition usually has no organic lesions, usually due to excessive eye use, the ciliary muscle to regulate the refractive spasm caused by the eye. Pseudomyopia occurs in adolescents. If the condition is not controlled, pseudomyopia may develop into true myopia in half a year or less, but in fact, pseudomyopia can be reversed. By paying attention to eye hygiene and correcting bad eye habits, it can be prevented from developing into true myopia. In order to prevent pseudomyopia from developing into true myopia, lifestyle interventions can be carried out through regular work and rest, maintaining good eye habits, increasing outdoor activities and doing eye exercises on a regular basis. If you are diagnosed with pseudomyopia, you should take appropriate measures under the guidance of your doctor to control it and try to prevent pseudomyopia from developing into true myopia.
