Method for determining vision correction equipment for a subject
A recently granted patent (Publication Number: US11927831B2) discloses a method for determining geometrico-morphological parameters of a subject in a natural posture to aid in vision correction equipment. The method involves placing the subject in a natural posture with their gaze directed towards a visual target, using an image capture apparatus to capture an image of the subject's head, and deducing the parameters from the captured image. The method includes steps such as adjusting the posture of the image capture apparatus relative to the subject's head, ensuring the gaze direction aligns with the visual target, and taking into account the distance between the image capture apparatus and the subject's eyes.
Furthermore, the patent also describes a system for implementing this method, which includes a visual target, an image capture apparatus, an adjustment system to position the apparatus correctly, and a calculator to deduce the parameters from the captured image. The system is designed to ensure accurate determination of parameters such as interpupillary distance, fitting heights, and the dominant eye of the subject. Additionally, the system includes features like a reference element for scaling the image, the ability to capture a three-dimensional image of the subject's head, and virtually fitting a frame for determining fitting height parameters. Overall, this patented method and system offer a comprehensive approach to determining geometrico-morphological parameters crucial for vision correction equipment based on capturing images of subjects in natural postures.
