The short answer
Orthokeratology, or Ortho-K, uses custom rigid lenses worn only during sleep to gently and temporarily reshape the front of the eye. Children and adults then see clearly all day without glasses or daytime contacts. At Riverdell Vision, Dr. Mina Han fits Ortho-K both for daytime freedom and as one of the most effective ways to slow the progression of a child's nearsightedness.

Why this matters
For active kids, glasses fog up, slip, and break, and daytime contacts are not always practical during sports and long school days. Meanwhile, a prescription that keeps climbing raises lifelong eye-health risk. Ortho-K addresses both at once: clear, correction-free days, and a slower rate of myopia progression.
Who this is for
- Children and teens who play sports or dislike glasses
- Families looking to slow myopia progression
- Adults who want daytime freedom without surgery
- Anyone not ready for, or not a candidate for, LASIK
