Understanding Overnight Vision Correction (OVC / Orthokeratology)
Overnight Vision Correction (OVC), also known as Orthokeratology, is a non-invasive service that uses specially designed contact lenses worn overnight to temporarily reshape the cornea and correct vision. Upon waking, users experience clear vision throughout the day without needing glasses or daytime contact lenses.
What is an Overnight Vision Correction Service?
An overnight vision correction service involves the prescription, fitting, and monitoring of custom gas-permeable lenses designed for overnight wear. These lenses gently flatten the cornea to correct refractive errors such as:
Myopia (nearsightedness)
Astigmatism (in some cases)
Progressive childhood myopia
The service allows patients to enjoy daytime freedom from eyewear and is popular among athletes, children, and individuals seeking non-surgical alternatives to LASIK.
What to Expect from an Overnight Vision Correction Service
When accessing this service, you can expect:
A comprehensive eye exam to determine eligibility
Custom lens fitting for your eye shape and prescription
Guidance on how to insert, remove, and clean the lenses
Follow-up appointments to monitor corneal changes and vision clarity
Adjustments as needed to ensure ongoing safety and effectiveness
The lenses are typically worn every night, with visual correction lasting 24–48 hours.
