Method for determining the adaptation of a myopia control optical lens

A method, implemented by a computer, for determining adaptation of a myopia control optical lens to a wearer, the myopia control optical lens being configured to provide simultaneously to the wearer a refractive optical function based on a prescription for said wearer and a myopia control function to reduce, delay, or prevent myopia progression of the wearer, the method comprising:

• obtaining an eye model corresponding to an eye of the wearer, said eye model comprising at least geometrical data relative to at least one structure of the eye model, an eye model rotation center, and at least one eye model optical axis passing through the eye model rotation center;
• obtaining a visual environment comprising at least a source object point and at least one object point;
• obtaining a myopia control optical lens model;
• obtaining a reference frame and positioning the eye model, the myopia control optical lens model, and the visual environment in the reference frame;
• determining at least one central vision quality criteria for at least one object point of the visual environment seen by the eye model through the myopia control optical lens model, wherein the determining the central vision quality criteria further comprises:
• determining at least one central gaze direction associated with the source object point,
• rotating the eye model around the eye model rotation center so that the eye model optical axis coincides with the central gaze direction,
• modifying at least one parameter of the eye model,
• calculating a central vision quality criteria based on the relative position of the source object point to the eye model rotation center within the reference frame, the myopia control optical lens model, and the modified at least one parameter of eye model, and
• optimizing the central vision quality criteria by repeating the modifying the at least one parameter of the eye model and the calculating the central vision quality criteria;
• determining at least one myopia control efficiency criteria for at least one object point(S) of the visual environment seen by the eye through the myopia control optical lens model;
• and
• determining the adaptation of the myopia control optical lens to the wearer based on the at least one central vision quality criteria and the at least one myopia control efficiency criteria.
