Visual Perceptions Eye Library | About Myopia (nearsightedness)

Myopia usually occurs between the ages of 8 to 12 years. Since the eyes continue to grow during childhood, nearsightedness almost always occurs before the age of 20. Often the degree of myopia increases as the body grows rapidly, then levels off in adulthood.
During the years of rapid growth, frequent changes in prescription eyewear may be needed to maintain clear vision. It is important to bear in mind that the frequent changes in prescription are not making the eyes \"weaker\".
