Computer Vision Syndrome


What effects do our eyes feel?

It’s alarming that, since 2007, new screens emit an average 5 times more high energy visible light (HEV) than previous technologies. The American Optometric Association named Computer Vision Syndrome (CVS), or Digital Eye Strain, the group of eye and vision-related problems that result from prolonged computer, tablet and cell phone use. Up to 80% of screens users report suffering from these symptoms.

Many individuals experience eye discomfort and vision problems when viewing digital screens for extended periods, even after stopping work at a computer. If nothing is done to address the cause of the problem, the symptoms will continue to recur and perhaps worsen with future digital screen use.

Sleep disorders

Numerous studies, such as the ones led by Harvard Medical School, link the emission of blue light to decreases in melatonin levels. This hormone regulates the circadian rhythm (our biological clock), that’s why more exposure to high energy light can affect our sleep negatively.
Worse, the studies have linked working late at night and direct over-exposure to high energy visible light can lead to certain types of diseases: breast and prostate cancer, diabetes, heart disease and obesity.

The risks you don’t notice

You are not aware of it, bu tour eyes are exposed to permanent damage and other symptoms that can mean serious consequences.

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.
