Red free photography is also regularly used as a base line photo prior to Angiography. [13] Angiography is a process of photographing/recording vascular flow within the retina and surrounding tissue by injecting a fluorescent dye into the blood stream. This dye fluoresces a different colour when light from a specific wavelength (excitation ...
Fundus photographs of the right eye (left image) and left eye (right image), as seen from the front (as if face to face with the viewer). Each fundus has no sign of disease or pathology. The gaze is into the camera, so in each picture the macula is in the center of the image, and the optic disc is located towards the nose. Both optic discs have ...
The eyes of most cephalopods, fish, amphibians and snakes have fixed lens shapes, and focusing is achieved by telescoping the lens in a similar manner to that of a camera. [5] The compound eyes of the arthropods are composed of many simple facets which, depending on anatomical detail, may give either a single pixelated image or multiple images ...
Whether you prefer a full makeup look or you favor a barely-there approach, for bigger, more wide-awake eyes in photos, you need to add some type of definition. "Using any kind of eyeliner adds ...
The vestibulo-ocular reflex is a reflex eye movement that stabilizes images on the retina during head movement by producing an eye movement in the direction opposite to head movement in response to neural input from the vestibular system of the inner ear, thus maintaining the image in the centre of the visual field. For example, when the head ...
A stereoscope presents 2D images of the same object from slightly different angles to the left eye and the right eye, allowing the viewer to reconstruct the original object via binocular disparity. When viewed with the proper vergence, an autostereogram does the same, the binocular disparity existing in adjacent parts of the repeating 2D patterns.
Floaters or muscae volitantes are slowly drifting blobs of varying size, shape, and transparency, which are particularly noticeable when viewing a bright, featureless background (such as the sky) or a point source of diffuse light very close to the eye. They are shadow images of objects floating in liquid between the retina and the gel inside ...
Optography is the process of viewing or retrieving an optogram, an image on the retina of the eye. A belief that the eye "recorded" the last image seen before death was widespread in the late 19th and early 20th centuries, and was a frequent plot device in fiction of the time, to the extent that police photographed the victims' eyes in several ...
