Abstract: A method and apparatus (100) for processing an image to determine one or more parameters of a contact lens suitable for a human or animal subject. The image comprises a plurality of pixels forming an image of at least part of one eye of the subject. The apparatus comprises: an iris detector (116) configured to determine a diameter of an iris of the subject; a cornea determiner (118) configured to determine a diameter of a cornea of the subject based on the determined diameter of the iris; and a contact lens determiner (120) configured to determine one or more parameters of contact lens for the subject based on the determined cornea diameter.

Abstract: An electronic device comprising a processor utility configured and operable for processing image data, determining whether an abnormality exists in an image of a subject's eye, and generating corresponding output data, said processor utility comprising: a first processor configured and operable for selecting in the image data an image comprising a region of interest including predetermined eye features of at least one of two eyes of the subject, the first processor further configured and operable for pre-processing the image to determine whether it is suitable for image processing and for providing an indication of the determined suitability of the image; an eye feature detection utility configured and operable for applying an image processing algorithm to a suitable image for determining one or more parameters of the eye features from a set of predetermined parameters; and an eye condition identifier utility configured and operable for processing and analyzing said one or more parameters and generating data

Abstract: A method for detecting strabismus in at least one image comprising a subject's eyes, wherein the at least one image has been obtained using an apparatus comprising a light source and a target offset from the light source, the method comprising, for each of the subject's left and right eyes: determining, from the image, a reflection offset distance, being the distance between a reference point of the eye and a reflection of a light source on the eye; determining a difference between the reflection offset distance and a reference reflection offset distance for the corresponding left or right eye, wherein the reference reflection offset distance has been determined based on relative positions of the light source, the target and the subject's head; and determining whether the difference is less than a difference threshold value for determining whether the subject has a strabismus.
