Computer Vision Syndrome


What effects do our eyes feel?

It’s alarming to note that, since 2007, new smart devices have been equipped with screens that emit, at an average, 5 times more high energy visible blue (LED) light than previous technologies.The American Optometric Association named Computer Vision Syndrome (CVS) or Digital Eye Strain, the cluster of eye and vision-related problems, result from prolonged computer, tablet and cell phone use. According to recent studies, up to 80% of screen users report suffering from these symptoms.

Many individuals experience eye discomfort and vision problems when viewing digital screens for extended periods, even after they stop working at a computer. It is important to recognize that if nothing is done to address the cause of the problem, the symptoms will continue to recur and perhaps worsen in the future with the ongoing digital screen use.

Sleep disorders

Numerous studies, such as the ones led by Harvard Medical School, link the emission of high energy blue (LED) light to decreases in melatonin levels. This hormone regulates the circadian rhythm (our biological clock) and that is why more exposure to high energy light can affect our sleep adversely. 
In addition to sleep disorders, studies have linked working with devices late at night and direct over-exposure to high energy blue light can lead to more acute diseases such as breast and prostate cancer, diabetes, heart disease and obesity.

The risks you don’t notice

You may not be aware of it however, your eyes are exposed to permanent damage and other symptoms that can mean serious consequences when you are staring at screens.

Groups at special risk



  1. Children lack the natural protective barrier that is not completely formed until the age of 25.
  2. They have shorter arms and therefore utilize electronic devices at a closer range.
  3. They also tend to focus at a closer range while using electronic devices, at proximity of 4 cm (approximately 2 inches).

Digital Workers

  1. Those who work in the high-tech industries are exposed to very high levels of blue light, averaging around 8-9 hours per day.
  2. The multi-screen effect. It is common for our eyes to be impacted by multiple screens at the same time.
  3. 73% of people in thyre 20's report synptoms of eye strain.

Senior Citizens and other groups at risk

  1. It is estimated that a increased percentage of senior citizens have or will have macular degeneration.
  2. As the years progress our eyes begin to deteriorate. It is important to maintain our eyes in good health considering the life expectancy increases every year
  3. Groups at risk: Any person who has any illnesses of the eye is at greater risk and must take appropriate steps to protect themselves.
