Hi , We Just Got My Son's Eye Checked ,

Hi , we just got my son's eye checked , he is 11 years old . As per family history neither me nor my wife are having spects

My son got -6 SPH in both the eyes and in left eye he also has -0.5 CYL number and Axis 150.

We need to seek your opinion that whether as the age increase what is the probability of number gets reduced. What are the other precautions we need to take to improve his eye sight to reduce the number . Thx Bims
