Abstract: A test to assess visual functions based upon the vision system's neuro-biological basis of vision requiring changes in stimulus. Multiple contrasting visual stimulus areas are varied by visual arc-area, color, contrast, velocity, strobic rate, size and relative sizes to test visual functions.

Abstract: Acuity is a function of the photoreceptors of the retina which combine their pixelized stimulation to create the perception of a contiguous image and use that stimulus to regulate the acuity focal length of the biological lens. That image perception is also modulated by the intensity of the light as a stimulus absorbed by those pixelized photoreceptors and, for most individuals, the color frequency of that light. The regulation of visual acuity is primarily determined by the comparative chromatic response of the cone photoreceptors in creating a response matrix to the relative chromatic intensity of the perceived light and using that response to regulate the focal length of the biological lens.

Abstract: Acuity is a function of the photoreceptors of the eye which combine their pixelized stimulation to create the perception of a contiguous image. The image perception is determined by the intensity of the light as a stimulus absorbed by those pixels and, for most individuals, the color frequency of that light. That image clarity is also a function of the density of the photoreceptors as recipients of that pixelized stimulation. Distance perception by the eye is enhanced by the relative clarity of the image, intensity or brightness of the image, and the relative size of the image in that when two similar images are in the same field of view, the larger of the images is perceived as being closer. Electronic displays emulate that photoreceptor stimulation with pixels that emit light such that the pixels density, when observed from a sufficient distance, gives the viewer the perception that the image is contiguous.

Abstract: A solution for targeting a visual function using varying contrasting areas is provided. An animation including a changing figure can be generated. The changing figure can include contrasting areas having attributes that change substantially continually during the animation. For example, a location of the contrasting areas within the changing figure can be changed to create an appearance of motion of the contrasting areas within the changing figure. The shape attributes can be determined based on a target visual function, a target performance level of the target visual function, and a plurality of display attributes of a display environment for an observer. The animation can be provided for display to the observer, and an indication of whether the observer is able to perceive the changes can be received and used to assess a performance level of the visual function.

Abstract: A system and associated methods for animated image vision testing is disclosed. In at least one embodiment, a vision test includes at least one animated dynamic optotype image for measuring the visual acuity of a subject. The animated image vision test takes advantage of the ability of the human eyes to detect both distance and motion. Moving images, such as rotating segmented circles, let the eyes detect motion as to the size, distance, and rotation direction of that moving image. That motion detection is much more precise than the interpretation of multiple static letters or static images. Using rotating images for vision testing rather than static images creates an acuity test more accurate than current tests, a test that is faster to use, and a test that does not require the ability to read.
