Lens flare on Borobudur stairs to enhance the sense of ascending. A lens flare is often deliberately used to invoke a sense of drama. A lens flare is also useful when added to an artificial or modified image composition because it adds a sense of realism, implying that the image is an un-edited original photograph of a "real life" scene.
Static and auras in vision, Palinopsia, Blue field entoptic phenomenon, Nyctalopia, Tinnitus: Complications: Poor quality of vision, Photophobia, Heliophobia, Depersonalization and Derealization [2] Usual onset: Visual Snow can appear at any time, but it commonly appears at birth, late teenage years, and early adulthood. Causes
When refractive errors in children are not treated, the child may be at risk of developing ambylopia, where vision may remain permanently blurry. [33] Because young children typically do not complain of blurry vision, the American Academy of Pediatrics recommends that children have yearly vision screening starting at three years old so that unknown refractive errors or other ophthalmic ...
Alcohol intoxication can cause blurred vision. Use of cycloplegic drugs like atropine [4] or other anticholinergics cause visual blur due to paralysis of accommodation. [3] Cataracts: Cloudiness over the eye's lens, cause blurring of vision, halos around lights, and sensitivity to glare. [5] It is also the main cause of blindness worldwide. [2 ...
Glare from artificial lights is typically measured with luminance meters. From daylit windows, cameras are used to convert the pixels into luminance. Both of which are able to determine the luminance of objects within small solid angles. The glare of a scene i.e. visual field of view, is then calculated from the luminance data of that scene.
Xanthopsia is a color vision deficiency in which there is a dominantly yellow bias in vision due to a yellowing of the optical media of the eye. The most common causes are digoxin's inhibitory action on the sodium pump, and the development of cataracts which can cause a yellow filtering effect.

[10] Gaming Bolt described the trend as a gimmick that had died with the generation, and criticised the heavy use of the technique in major releases of the time such as The Elder Scrolls IV: Oblivion (2006), the Xbox 360 port of ...
Image on the left has exposure time of >10 seconds in low light. The image on the right has adequate lighting and 0.1 second exposure. In low light, correct exposure requires the use of slow shutter speed (i.e. long exposure time) or an opened aperture (lower f-number ), or both, to increase the amount of light (photons) captured which in turn ...
