摘要:
A device for training and testing dynamic visual acuity is provided. The device comprises an object that is tethered using a connector, such as a string. The object may display one or more visual indicia with a given characteristic. Examples of visual indicia may include letters, numbers, shapes, and the like. Additional exemplary characteristics of the visual indicia may include varying sizes and contrasting colors. Once tethered, the object can be put into motion, which causes the subject to use more effort in viewing and identifying the visual indicia on the device.
