Solutions In Sight - Comfort Drop Reminder

Our eyes are protected and maintained by a bodily system involving lubricating and protecting fluids, protective tissue and automatic muscle responses called blinking.

The eye itself is coated with three distinct layers of fluid, which together are called the "tear film". The inner layer of mucous lubricates the cornea (the clear front surface window of the eye) and prepares it for uniform moistening. The middle water layer keeps the cornea moistened and optically uniform. The outer layer is produced by the oil glands within the eyelid. This outer layer slows the process of tear evaporation.

Long work sessions at the computer terminal can lead to an uncomfortable dryness of the eyes. This is because of the reduced blink rate and the posture adopted when viewing the VDT. Firstly, when using a VDT, one tends to blink less than when performing other tasks. That means the eye gets moistened less often.

Additionally the posture typically adopted when using a VDT contributes to dry eye. When reading text on paper, one's head is normally tilted down. As a result, the eyelids cover a good portion of the eye. When using a VDT however, one's head is erect and the eyes are open wider. The evaporation of the the tears increases when the eye is opened wider. This results in a higher risk of dry eye. Dry eye can be particularly bothersome for contact lens wearers, and is more likely to be a problem as one gets older.

For the discomfort caused by dry eyes, ocular lubricant eye drops may be indicated. The drops should be used to rewet the eye surface before discomfort occurs.

Included in the Solutions In Sight system is a Windows-based software program, designed to remind you when to pause to use these drops to minimize discomfort and promote eye health.
