Ortho-K for children, ages 7–18
Your child sleeps in highly oxygen-permeable, semi-soft lenses. In the morning, they take them out and see clearly. Ortho-K slows nearsightedness as children grow, and for children with a family history of nearsightedness it is the best option for effective control.
Night
Is your child’s prescription going up every year?
Nearsightedness often gets worse during the school years. Stronger glasses fix the blur, but they don’t slow the change.

Wearing Ortho-K lenses: tips from our office
Common while your eyes adjust
- Halos or glare at night
- Blinking more often
- Discomfort from dust or tissue fibers in the eye
- Take the lens out and clean it again.
- A lens that moves off center, from rubbing the eyes or moving them quickly
- A lens that slides up or down
- Keep your eyes open, look down or up to find the lens, and take it out.
- Itchy eyes
- Don’t rub your eyes. Use the corneal care drops for quick relief.
- Place a tissue dampened with water or ice water over the eyes.
How to keep eye infections away
- Always wash your hands before putting in or taking out the lenses, so germs on your hands don’t get onto the lenses.
- Don’t pour lens-care solution into other bottles, and replace your lens-care supplies regularly.
- Keep the bathroom sink dry and clean.
- Two things to keep in your pocket: moisturizing eye drops and lip balm. When your lips feel dry, your body is starting to run short of water. Remember to drink plenty of water!
- Keep the cornea moist to help fight off germs.
- Never rub your eyes.
- Wear sunglasses that block blue light when you go out.
- After swimming, always use the corneal care drops to moisten the cornea and help it recover.
- If the eyes look red or bloodshot, stop wearing the lenses right away, rest, and call us.

Parent questions
Is Ortho-K safe for kids?
Ortho-K is a safe choice for children when an eye doctor fits the lenses and your family cares for them exactly as instructed. Like any contact lens worn overnight, it carries a small risk of eye infection, which can be serious. You can keep that risk low by washing your hands before touching the lenses; cleaning and storing them only with the solutions we give you, never with tap water; replacing the case and lenses on schedule; and coming to every follow-up visit so Dr. Woo can check your child’s eyes. If your child has eye pain, redness, sensitivity to light, discharge, or blurry vision that doesn’t clear, take the lenses out and call us right away at (800) 991-8881.
