Question: Why did my friend’s child still increase by -0.25D after a year with these lenses?
Myopia Control Glasses
Answer: That’s a great question. We have to look at "how much would it have increased without them?" If the child was projected to increase by -1.00D but only increased by -0.25D, that is a 75% success. Every child’s genetics and environment differ; our goal is to "slow down," not necessarily "stop" growth completely.
