Invest in Your Child’s Eyes to Help Them Realize Their Full Potential

Especially when caught early, myopia is manageable – and not just with stronger and thicker glasses.

Euclid Emerald is a modern design of Ortho-K lenses for myopia management. This advanced technology is proven on nearly 2 million eyes around the world.

Lenses Designed Just for Your Child’s Eyes

This gentle, non-surgical solution uses specially designed contact lenses that reduce the effect of myopia with continuous overnight wear. Similar to a custom dental retainer from an orthodontist, worn overnight to correct the alignment of teeth, Euclid Emerald lenses are made specifically for your child’s unique eyes, and they work comfortably to gently reshape the cornea to correct vision while they sleep.

Once these overnight corneal reshaping lenses are removed in the morning, your child’s eyes naturally maintain their shape, so your child has clear vision all day, without the need for daytime corrective lenses or glasses. To maintain the effect of myopia reduction, overnight lens wear must be continued as prescribed by your doctor.

Euclid Emerald lenses are the only Ortho-K lenses made with MyoKTM Design.

Each lens is designed to be the perfect match for your child based on the unique shape, measurements and prescription of their eyes, giving your child the best possible outcome.

How it Works

The best part about Euclid Emerald myopia management treatment is how easy it is for your child.

They just put Euclid Emerald lenses on before bed and go to sleep while the lenses comfortably work to gently reshape the cornea overnight. Because they’re only worn at night, it’s easy to supervise your child’s use of Euclid Emerald lenses. Once awake, your child sees clearly all day.

Who Are They For?

Euclid Emerald Treatment is ideal for any child with healthy eyes and the desire to help prevent their myopia from getting worse.

Euclid Emerald contributes to a life without daytime contact lenses or glasses for nearsightedness. Parents are encouraged to start early, as young as age 6.
