The age of eye fixation is routinely referred to after the age of 18, which is after the end of the senior year of high school, and is generally a vague value. Not everyone’s eyes don’t grow or elongate after the age of 18, but this is a statistical probability. Most people’s myopia stabilizes and does not grow after the age of 18, but in a very small number of people, or those with high myopia, there is no age limit for eye fixation. High myopia is related to genetics, it grows every year, not after the age of 18, but the axis of the eye will gradually lengthen with age. Therefore, myopia can exceed 600 degrees, even 700-800 degrees, and it is growing every year.
