# Ortho-K night lenses: clear daytime vision and myopia control at Lumos Vision ![Ortho-K night lenses: clear daytime vision and myopia control at Lumos Vision](https://bigmed.ge/media/serve/media/blog/original/wUuMTRlQ7pPsIwEMPeCDooe3yuX3sVHcZYX4qpzi.png) **Specializations:** Eyes, Ophthalmology > A Lumos Vision partner feature about Ortho-K night lenses, daytime freedom from glasses, childhood myopia control, and the diagnostics behind a safe, personalized fitting. Partner feature Picture a normal morning: a child removes their night lenses and heads to school, sports practice, or the playground without glasses. An adult drives, works, and stays active without daytime contact lenses. That is the practical appeal of orthokeratology, also known as Ortho-K. Special rigid gas-permeable lenses are worn during sleep and removed after waking. Overnight they temporarily alter the optics of the front surface of the eye. For many people, the payoff is clear daytime vision and greater freedom of movement. In children with progressive myopia, Ortho-K may also be selected to slow axial eye growth. ## The lenses work overnight; you use the result during the day With myopia, light focuses in front of the retina, making distant objects appear blurred. An Ortho-K lens does not stay on the eye all day. During sleep, it acts through the tear film on the corneal epithelium according to a precisely calculated profile. After removal, the temporary change in corneal curvature improves the focus of light. ### What happens overnight **☾ Sleep in the lenses** The lens interacts with the tear film and corneal epithelium according to the profile calculated by the doctor. **◉ Remove them in the morning** The corneal optics change temporarily, bringing the focus of light closer to the retina. **☀ A day without glasses** Many patients see clearly at distance without daytime lenses. The duration of the effect varies. The effect is reversible. Once lens wear stops, the cornea gradually returns to its original shape. A doctor therefore sets an individual wearing and follow-up schedule. Some people maintain the correction throughout the day, while others notice it fading earlier. ## Why parents ask about Ortho-K for childhood myopia Standard glasses provide a clear image, but not every form of optical correction is designed to slow myopia progression. When myopia begins early, doctors monitor more than the prescription. Axial length, the distance from the front of the eye to the retina, is an important objective measure. The International Myopia Institute's 2025 review places orthokeratology among the most effective optical myopia-control methods. Across ten randomized trials, the median reduction in axial elongation was **0.17 mm at one year** and **0.30 mm at two years** versus control groups. These are median research findings, not a guaranteed result for an individual child. **What the doctor measures** At Lumos Vision, axial length is measured with optical biometry at baseline and over time. This allows decisions to follow measurable change rather than the spectacle prescription alone. ## Safe fitting begins with diagnostics A night lens must match the geometry of the individual cornea. It cannot be bought using someone else's prescription or fitted approximately. Before calculating the design, the doctor checks refraction, the anterior eye, the tear film, and corneal topography. After fitting, patients or parents learn how to insert, remove, and clean the lenses. Follow-up is part of the treatment. The doctor checks lens fit, vision quality, corneal health, and changes in axial length. If Ortho-K is not suitable, Lumos Vision can discuss alternatives such as myopia-control spectacles, specialized soft contact lenses, or a medication strategy when indicated. ## What Lumos Vision offers Lumos Vision is an ophthalmology clinic and myopia-control center in Tbilisi. It was founded in 2023 by ophthalmologist and orthokeratologist [Natia Dediashvili](https://bigmed.ge/en/doctors/dediashvili-natia). The clinic sees children and adults, uses corneal topography and optical biometry, and fits Ortho-K, defocus soft, rigid gas-permeable, and scleral lenses. - Vision diagnostics and assessment of myopia progression. - Personalized design and fitting of Ortho-K lenses. - Care training and follow-up visits after wear begins. - An electronic examination report with results and recommendations in the patient's language and Georgian. Address: 20 Tskneti Highway, Tbilisi. Open daily from 10:00 to 19:00. Phone: [+995 591 96 25 99](tel:+995591962599). ## Find out whether Ortho-K is right for you Book a diagnostic visit at Lumos Vision. The doctor will examine the eye, explain the likely effect and risks, and suggest a personalized correction or myopia-control plan.

Poor hygiene raises the risk of irritation, corneal injury, and infection. Never rinse lenses with water, wear them beyond the prescribed schedule, or skip follow-up examinations. **Remove the lens and seek prompt professional care** for pain, marked redness, light sensitivity, discharge, sudden blur, or reduced vision. Do not wear the lens again before examination. This advertising and informational partner feature was prepared with Lumos Vision. It does not replace an ophthalmology consultation. Indications, contraindications, wearing schedule, and expected outcomes are determined after diagnostics. ## FAQ ### Can I go without glasses during the day after Ortho-K? Many patients see clearly at distance after removing the lenses in the morning. The duration of the effect varies by person. ### Do night lenses cure myopia permanently? No. The corneal optical change is temporary and reversible. Lenses are worn on the schedule prescribed by the doctor to maintain correction. ### Why is a child’s axial eye length measured? Axial length provides an objective way to monitor myopia progression and assess the selected control strategy. ### Who may not be suitable for Ortho-K? A doctor determines contraindications. Active inflammation, certain corneal conditions, significant dry eye, or inability to follow care rules may prevent wear. **Reviewed by doctor:** Dediashvili Natia: https://bigmed.ge/en/doctors/dediashvili-natia (2026-09-01) ## Recommended doctors - Dediashvili Natia — Ophthalmologist, Neuro-ophthalmologist, Orthokeratologist: https://bigmed.ge/en/doctors/dediashvili-natia (markdown: https://bigmed.ge/en/doctors/dediashvili-natia.md) --- Canonical: https://bigmed.ge/en/blog/nochnye-linzy-ortho-k-lumos-vision Country: Georgia (GE), the country in the South Caucasus Published: 2026-09-01T12:02:23+04:00 Updated: 2026-09-01T13:55:34+04:00
