Things to Know about Ortho-k Lenses

If you or your child have been diagnosed with myopia and are looking forward to getting ortho-k lenses fitted by our professional optometrist, here are a few things you would want to know.

Are Ortho-k Lenses Safe?

The FDA as well as Health Canada have approved these lenses for the reshaping of the cornea. The gas-permeable material used in these lenses helps oxygen reach the surface of your eyes at night. Just like other contact lenses, you should clean and disinfect these before wearing them at night.

Are Ortho-k Lenses Effective?

Ortho-k lenses start taking effect as soon as you start wearing them, and 50% of the prescription is eliminated after just one night. The remaining prescription is typically reduced in under a fortnight. These lenses can also slow down the glasses prescription of children suffering from myopia by around 40-70%.

Are Ortho-k Lenses Comfortable?

These lenses are pretty comfortable to wear throughout the night. They do not press directly on the surface of your eye and sit on the tear film instead.

Are Ortho-k Lenses Durable?

The lenses may begin to change shape after a year of regular use. The alteration will affect the lenses’ ability to reshape the cornea. It is at this point that you should get your ortho-k lenses replaced by us.


Myopia patients can see clearly during the day by wearing ortho-k lenses at night.
