Night Lenses

Orthokeratological lenses (OK-lenses) are a method based on the use of special gas-permeable contact lenses that are worn exclusively during sleep. Under the precisely calculated impact of the lens, the corneal epithelium (its surface layer) changes its shape overnight. The impact of the lens is minimal and not harmful to the eye, however, it is sufficient for the refractive power of the cornea to change by the required amount after sleep, and the visual acuity becomes close to or equal to 100%. This effect lasts all day and gradually fades over several days. Sleeping in lenses does not cause discomfort.

Who benefits from Night Lenses?

OK-therapy is used to correct myopia (from 0.5 to 8 diopters), hyperopia (from 0.5 to 4 diopters), astigmatism (from 0.5 to -5 diopters) and presbyopia, as well as when these refractive disorders are combined ( myopia + astigmatism, hyperopia + astigmatism, myopia + presbyopia, etc.). Unlike other correction methods such as laser surgery, OK therapy is suitable for children from 6 years of age and adults of any age.

What correction methods allow you to see well without glasses

To see well, there are several correction methods.

Orthokeratology (OK-therapy) is the only vision correction method that does not require glasses or contact lenses during the day, or resort to surgery in order to have excellent vision. Special contact lenses for OK therapy are used only during sleep. While we sleep, our cornea adapts to the lenses until our vision is completely corrected. When we wake up, we take off our lenses and can see well all day.
