After the age of 18, adult prescriptions generally do not grow once they stabilize, but it depends on whether you are still in school. If you still work at close range and suffer from eye strain, your eye prescription may still grow.

When you are young, your eyes are a little nearsighted and a little farsighted, because the ciliary muscle itself has a regulating function. Therefore, adult myopia will not develop further, unless after the age of 45, a little bit of farsightedness, will be blurred, look at the near vision will become worse.
