Visual Stress and Technology

A study published by the New York Times in 2009 revealed adults are exposed to screens – TV, cell phones, computers, etc. – roughly eight and a half hours on any given day.

Even the smallest uncorrected prescription can cause problems at the computer. This is especially true if you happen to be far-sighted or have astigmatism, due to the excessive focusing required to maintain a clear image.
Dry eyes and poor tear quality can cause blur and eye discomfort. We tend to blink less often when viewing the computer allowing the tears to evaporate.

Some solutions to eyestrain at the computer or with other digital devices  include a correction specific for the task. For example, a pair of computer glasses designed with optimal correction at the distance to the digital display and including appropriate coatings and tints to reduce strain and improve efficiency.

Reducing glare from overhead lights and windows will minimize squinting. Simply adjusting the screen position, closing window blinds and decreasing the wattage of a desk lamp will reduce glare. To see an earlier post with more details click here.
