Abstract: A device for screening for autism spectrum disorder includes a housing configured for portable use, one or more cameras mounted to the housing, and one or more light sources mounted to the housing. The device captures a video of one or more eyes using the one or more cameras, emits a light stimulus using the one or more light sources, and synchronizes the video to the light stimulus. The device analyzes the video for measuring a pupillary response to the light stimulus. The device compares the pupillary response to one or more metrics. The device generates an output based on comparing the pupillary response to the one or more metrics, the output including a recommendation related to autism spectrum disorder.

Abstract: A vision screening device for administering vision screening tests to a patient, to determine the presence of diseases and/or abnormalities in the eye(s) of the patient, is described herein. The vision screening device may include associated methods and systems configured to perform the operations of the vision screening tests. The device may include a radiation source configured to generate near-infrared (NIR) radiation, a sensor configured to capture a grayscale image representing the radiation reflected by the eye(s) of the patient, a white light source, and a camera configured to capture a color image of the eye of the patient. The device may also be configured to generate a composite image based on the grayscale image and/or the color image, determine a difference between a value associated with the eye and an expected value, and generate an output indicative of a condition associated with the eye(s) based on the difference.

Abstract: A vision screening device displays visual stimuli and captures image(s) of the eye while the visual stimuli is changing over a period of time. The vision screening device uses the images to determine and monitor refractive error, ambient light level(s), pupil size, and gaze angle as the visual stimuli changes over the time period. Based on the refractive error, a determination of hyperopia and/or presbyopia is made. Based on the gaze angle and/or the pupil size, a confidence metric is determined. Based on the confidence metric and/or the determination, a recommendation for the patient is generated and displayed.

Abstract: A vision screening device captures image(s) of reflected radiation from light source(s) and uses the images to determine a cornea curvature. The light source(s) may comprise infrared LEDs and be configured in a predetermined pattern. Based on the cornea curvature, an axial length is determined and/or a prescription for a patient is determined. Other characteristics of the patient may be used to determine axial length. Based on the axial length, a recommendation for the patient is generated and displayed.

Abstract: A vision screening device for administering vision screening tests, and in particular a color vision screening test, to a patient is described herein. The vision screening device may include associated methods and systems configured to perform the operations of the vision screening tests. The device may include a first radiation source configured to generate color stimuli, a second radiation source separate from the first radiation source configured to emit near-infrared radiation, and a sensor configured to capture the near-infrared radiation emitted by the second radiation source, and reflected by an eye of a patient. The device may also be configured to cause color stimulus to be displayed to the patient, and determine measurement(s) of the eye of the patient in response to the color stimulus. The device may be further configured to analyze the measurements to generate a recommendation and/or diagnosis associated with the vision of the patient.

Abstract: An airfield light includes a light assembly mounted on a base and a transparent cover disposed over the light assembly and secured to the base. The light assembly includes a curved LED (light emitting diode) assembly having a circuit board with at least a portion that is curved along its length. A plurality of LEDs are spaced apart along the length of the circuit board and are configured to emit light through the transparent cover.
