The present invention provides a system, apparatus, and method for preventing Computer Vision Syndrome (CVS) that addresses the various causes of CVS. To help maintain a proper preocular tear film the present invention provides a device to generate a blink reminder signal and a blink indicator, such as a light, a speaker, or a portion of a display monitor, to communicate the blink reminder signal to the computer user. The device may incorporate feedback devices such as a blink monitor, a temperature monitor, a humidity monitor, an elasped time monitor, or a clock. The present invention also provides an eye enclosure that defines an enclosed area about the computer user's eye that is at least partially enclosed. The invention incorporates components aimed at optimizing the environment within the enclosed area. For example, air moisterners communicating with the enclosed area maintain a relatively high humidity within the enclosed area and reduce the evaporation of fluid from the eyes. The moistening fluid may be adapted to the particular needs of the individual and other conditions, such as temperature, may also be controlled. Also, the composition of the tear film may be manipulted using the moistening fluid or a small pellet placed in the cul de sac of the user's eye to help maintain a proper tear film or otherwise change the tear film characteristics.
