How long does it take for pseudo-myopia to become true myopia?

Generally, the time it takes for pseudo-myopia to progress to true myopia is not fixed. If there is excessive eye use and limited outdoor activity, the transition may occur within two months to one year. In adults, improper eye use may lead to progression to true myopia in approximately two years. Detailed analysis is as follows:

Continuous prolonged near-eye work without sufficient eye relaxation may cause pseudo-myopia to develop into true myopia within two months. If good eye habits are maintained, pseudo-myopia may remain stable for a long time, and vision may even return to normal; it may not necessarily progress to true myopia. Individuals with limited outdoor activity may be more prone to the progression of pseudo-myopia to true myopia due to insufficient natural light stimulation, potentially within one year. If 1–2 hours of daily outdoor activity can be ensured, the progression of myopia can be effectively delayed, reducing the likelihood and prolonging the time of transformation from pseudo-myopia to true myopia.

In adults, eye development is relatively mature. Although pseudo-myopia can still occur, its progression to true myopia is usually slower, potentially taking two years or longer, and pseudo-myopia may even persist for a long time without progressing.

Maintaining good eye habits and increasing outdoor activity time are important measures for delaying the progression of pseudo-myopia to true myopia.
