Abstract
A method of slowing the progression of myopia in a person, comprises applying to the eye of the person contact lens or lenses each including a vision correction area for correcting in use the myopic vision of a wearer, and a myopic defocus area having a less negative focal power, to simultaneously present a controlled myopic defocus to the retina both when viewing in the distance and also when viewing at near. Contact lenses and their use are also claimed.
