Abstract
An ophthalmic apparatus comprises an optical arrangement that causes or imitates, for forming at least one image that is in focus, a longitudinal chromatic and/or spherical aberration of an optical spectrum of light, while the retina is configured to locate within a longitudinal aberration range of the aberration in response to a distance between the ophthalmic apparatus and the eye being within a working range of the ophthalmic apparatus. An image capturing arrangement captures one or more images of the retina through the imaging channel while the distance between the ophthalmic apparatus and the eye is within a working range of the ophthalmic apparatus. A filter filters at least one image from the one or more images of the retina that is in focus for further processing in a data processing unit of the ophthalmic apparatus.
