Problems solved by technology

[0004] Conventional ophthalmic cameras have a small shooting range. For fundus shooting, the imaging range is generally within 60 degrees. It is necessary to hold specific equipment to shoot room angles.
Moreover, this ophthalmic camera is huge in size and expensive, and is not suitable for portability.
Even hand-held ophthalmic cameras have the problems of small imaging range and high equipment prices

Abstract

The invention discloses an ophthalmic photographing method. The method comprises the steps that an ophthalmic contact lens is placed above a shooting object, then the shooting object is imaged by the ophthalmic contact lens and then reflected; and the camera shoots the imaging content of the ophthalmic contact lens. According to the scheme provided by the invention, the ophthalmic contact lens is adopted to image the shot object and then reflect the shot object. The camera is located in the reflection area of the ophthalmology contact lens, and through reflection of the ophthalmology contact lens, the camera can shoot the reflection range of the ophthalmology contact lens. In the shooting process, the whole shooting object can be scanned by rotating the ophthalmic contact lens. Therefore, a large-range imaging result can be captured, and wide-angle shooting is realized.

Description

[0001] Information about divisional applications [0002] This case is a divisional application. The parent case of this divisional case is an invention patent application with an application date of May 22, 2019, an application number of 201910429485.9, and an invention title of "an ophthalmic photographing device and an ophthalmic photographing method". technical field [0003] The invention relates to the technical field of photographing eyes, in particular to an ophthalmology photographing method. Background technique [0004] Conventional ophthalmic cameras have a small shooting range. For fundus shooting, the imaging range is generally within 60 degrees. It is necessary to hold a specific device to shoot the room angle. And this ophthalmic camera volume is huge, and cost is expensive, is not suitable for portable. Even hand-held ophthalmic cameras also have the problems of small imaging range and high equipment price. [0005] Therefore, how to increase the imaging ...
