Question: What if the power still increased by -0.25D or -0.50D? Does it mean the lenses failed?
Myopia Control Glasses
Answer: Not at all. We must compare this to the "uncontrolled" scenario. Without these lenses, the increase could have been -1.00D. As long as the rate of progression has slowed down, the treatment is working. Our goal is "slow down," not necessarily a total "stop," because as children grow taller, a certain amount of physiological eye growth is normal.
