What are the benefits of orthokeratology overnight wear?

Orthokeratology overnight wear specifically involves the use of custom-designed gas-permeable contact lenses that are worn while sleeping. The primary benefit of this treatment is that it reshapes the corneal curvature overnight, allowing individuals to enjoy clear vision during the day without the need for glasses or contact lenses. This effect is particularly beneficial for those who may not want to wear corrective lenses during the day due to lifestyle preferences or professions that require clear vision without hindrance.

While other benefits exist in broader contexts—such as possibly reducing the need for surgical interventions in certain refractive cases—this is not the primary purpose of orthokeratology. Similarly, while color perception can be affected by overall vision clarity, orthokeratology does not specifically enhance color perception itself. Additionally, the prevention of lens-related infections typically pertains to standard contact lens wear rather than orthokeratology, where the lenses are only worn overnight and not during waking hours.

Thus, the correct answer highlights a key advantage of orthokeratology: the ability to achieve clear daytime vision without relying on conventional vision correction, which is a significant appeal for many patients opting for this treatment.
