How long will it take to achieve good vision after I am initially fitted with OrthoK?
Vision improvement starts immediately. You may notice it within a few minutes. It is very significant within two hours. Some patients see clearly in as little as one night of wearing OrthoK retainer lenses. Vision is normally good during all waking hours within the first week. In some adults with higher prescriptions, it can take two to four weeks to achieve good vision. Because children’s eyes are more easily molded, vision improvement generally takes effect more rapidly than it does for adults.
