How Peripheral-Defocus Lenses Work
Myopia gets worse when the eyeball grows too long from front to back. Research suggests that where peripheral light comes to focus can influence that growth: in a nearsighted eye, ordinary lenses often focus the peripheral image behind the retina, which may signal the eye to keep elongating.
Peripheral-defocus myopia lenses — the category Euclid BeFree belongs to — keep the central vision clear while reshaping the peripheral optics to bring that off-axis light in front of the retina. That shift is thought to create a braking cue that slows elongation. It’s the same underlying principle behind several treatments Dr. Patel already offers, including MiSight 1 Day and Stellest spectacle lenses.
Important: Euclid BeFree is not FDA-approved for myopia control in the United States. This information is educational and is not a recommendation or an offer to provide a non-approved device. Any myopia-management decision is made individually with Dr. Patel based on your child’s exam and the treatments appropriate and available to them.
