Do I have to wear orthokeratology lenses for 8 hours a day?

Orthokeratology is a special contact lens that reshapes the cornea when worn at night, thereby achieving clear naked eye vision during the day. However, the saying that orthokeratology lenses must be worn for 8 hours a day is not absolute.

The wearing time of orthokeratology lenses is related to individual differences. Each person's corneal morphology and physiological characteristics are different, so the wearing time will also be different. Some people's corneas may be easier to reshape, and only need a shorter wearing time to achieve the ideal vision effect; while others need to wear them for a longer time to achieve the same effect.

Secondly, the wearing time of orthokeratology lenses is also related to the correction goal. If it is just to control the progression of myopia, the wearing time may be relatively short; if you need to achieve the ideal naked eye vision effect, you need to wear it for a longer time.

In addition, orthokeratology lenses need to be worn for a certain period of time to ensure corneal stability and lasting improvement in vision. If they are not worn for an adequate period of time, the corneal morphology may become unstable, affecting lasting improvement in vision.

Although it is not absolutely required to wear orthokeratology lenses for 8 hours a day, in order to ensure lasting improvement in vision and corneal health, it is recommended that wearers maintain a sufficient wearing time according to the advice of doctors or professionals. At the same time, wearing orthokeratology lenses also requires following correct hygiene habits and wearing methods to avoid eye discomfort or complications.
