Question: Can glasses really use "light" to change the way an eye grows?
Myopia Control Glasses
Answer: Yes, the science is based on "Defocus Feedback." The eyeball is intelligent and grows toward where light is focused. Normal glasses focus peripheral light behind the eye, causing the eye to stretch to "catch" it. Control lenses are embedded with hundreds of lenslets (Treatment Zones) that create a "curtain of light" in front of the retina. This acts like a "firewall" against growth, effectively curbing excessive axial elongation.
