I have seen these lubricants make a dramatic difference in the eyes of computer users. During the day while contacts are worn, if you feel like an eyelash is touching this is the first stage of dryness. One drop in the eye is sufficient, in just a few blinks the refreshment should occur and last for a number of hours. The second stage of contact lens dryness will be a blink, momentarily the vision is fuzzy and with the next blink vision is restored. Drops are not habit forming or addictive.
Computers pose a specific demand for contact lens wearers.
Remember head position must not be tilted downward as this will decrease blink rate. Increase screen illumination for your eyes focus better upon a brighter source especially as you get older. Keep documents either in front of you or on your dominant side of the CRT screen. Dry Eye Visual difficulties related to Computers are the number one complaint by workers who depend on computers for their business activity. These body postures place more pressure and stress on your neck, shoulders, and back.
