Stereo-acuity Ability to perceive spatial TNO Stereo depth; it is a binocular test faculty which is achieved through horizontally disparate images for right & left eyes of the same object Test Illumination, Scale lux Static visual acuity 480 Letter score (theoretical range: 0 to 100) Refractive error 12 Spherical and cylindrical error with axis (Diopter) Contrast sensitivity 12 Log Unit Ocular alignment Photopic [greater Prism Diopter than or equal to] 25 Stereo-acuity 800 Range: 15 to 480 s/arc Test Description Static visual acuity Monocular and binocular visual acuity and best spectacle-corrected visual acuity (BSCVA) are assessed and recorded during archery Refractive error This measurement is performed with and without cycloplegia.
Neurovision studies have reported behavioral changes related to ingestion of alcohol, for example: (i) changes in perception and detection of asymmetry of facial expressions in both men and women (Oinonen & Sterniczuk, 2007); (ii) change in luminance processing speed in photopic and scotopic levels (Khan & Timney, 2007; Puell & Barrio, 2008).
The proportion of shorter wavelength 'scotopic' light relative to longer wavelength 'photopic' light is known as the S/P ratio.
In photopic vision, our fovea is more sensitive to the red wavelength while the blue wavelength influences scotopic vision.
