Glare assembly for computerized eye test display

摘要

A monitor is used to display a visual acuity test operated by software from an associated computer. A patient is spaced a predetermined distance from the monitor during the testing procedure, and individual, multiple LED housings are equally spaced about a center point of the monitor to direct light toward the patient during at least a portion of the test procedure. The light emanating from the individual housings is a diffuse, unfocused light to simulate glare, and the intensity of the light may be selectively altered. Conducting acuity testing under glare conditions determines if there is any reduction or fall off in the patient's acuity vision under such circumstances and provides an indication of whether the patient may require cataract surgery or has another ocular problem.

主权项

1. A computer vision testing system comprising:
a monitor for displaying an eye test procedure; and at least first, second, third, and fourth diffuse, unfocused light sources equi-spaced about a center point of the monitor and directed toward an associated patient to conduct the test procedure displayed on the monitor under glare light conditions, wherein at least the first and second light sources are disposed above and below the monitor, and at least the third and fourth light sources are disposed along first and second sides of the monitor wherein the light sources each simultaneously emit diffuse, unfocused light for both eyes.
