Ortho-K vs. Traditional Contact Lenses: Which is Right for You?

Contact lenses are popular for those looking to improve their vision without glasses. However, different types are available, including traditional soft and Ortho-K lenses. In this article, we will compare and contrast Ortho-K and traditional contact lenses and helps you decide which the right choice is for you.

What is Ortho-K?

Ortho-K, or Orthokeratology, is a non-surgical, reversible vision correction method that uses specially designed gas-permeable lenses to reshape the eye’s cornea while you sleep. The lenses gently flatten the cornea, correcting nearsightedness, astigmatism, and presbyopia.

How do traditional contact lenses work?

Traditional contact lenses, on the other hand, work by sitting directly on the eye’s surface. They are made from a soft, flexible material that conforms to the shape of the eye to correct vision problems.

Comfort and Convenience

One of the biggest differences between Ortho-K and traditional contact lenses is soothed and convenient. Traditional contact lenses can be worn throughout the day, but they can cause dryness, irritation, and discomfort, especially in people with dry eye syndrome. They also require daily cleaning and storage.

Ortho-K lenses, however, are worn only at night while sleeping, providing clear vision during the day without any discomfort. Additionally, they do not require daily cleaning, making them a more convenient option for those with busy schedules.

Vision Correction

Ortho-K lenses provide a unique vision correction different from traditional contact lenses. They temporarily reshape the cornea, providing clear vision during the day without needing glasses or contact lenses. However, they are only effective for low to moderate levels of myopia, with some studies suggesting a limit of -6.00 diopters.

Traditional contact lenses, on the other hand, can correct a wider range of vision problems, including astigmatism and presbyopia. They also offer a wider range of prescription strengths and are available in daily or extended wear options.


The cost of Ortho-K lenses can be higher than traditional contact lenses due to the specialized gas-permeable material and the additional cost of the fitting process. However, in the long run, Ortho-K can be more cost-effective as there are no ongoing costs for cleaning and replacing lenses.


Ortho-K and traditional contact lenses are generally considered safe when used as directed. The Qualified optician optometrist gives better guidance in choosing. However, there is a slightly higher risk of infection with traditional contact lenses due to the need for daily cleaning and storage.

Bottom line

Ortho-K and traditional contact lenses offer different options for vision correction. While traditional contact lenses may be a better option for those with more severe vision problems or who need to wear lenses throughout the day, Ortho-K can offer a more convenient and comfortable option for those with mild to moderate myopia who want clear vision without glasses or contact lenses during the day. Ultimately, the decision of which option is best for you should be made with the help of your qualified optometrist or optician based on your individual needs and lifestyle.
