COMPUTER VISION SYNDROME

Computer Vision Syndrome, also referred to as Digital Eye Strain, describes a group of eye and vision-related problems that result from prolonged computer, tablet, e-reader and cell phone use. Many individuals experience eye discomfort and vision problems when viewing digital screens for extended periods. The level of discomfort appears to increase with the amount of digital screen use.

Viewing a computer or digital screen often makes the eyes work harder. As a result, the unique characteristics and high visual demands of computer and digital screen device viewing make many individuals susceptible to the development of vision-related symptoms.

The most common symptoms associated with Computer Vision Syndrome (CVS) or Digital Eye Strain are

· Eyestrain

· Headaches

· Blurred vision

· Dry eyes

· Neck and shoulder pain


These symptoms may be caused by:

· Poor lighting

· Glare on a digital screen

· Improper viewing distances

· Poor seating posture

· Uncorrected vision problems

· A combination of these factor


Our eyes are exposed to increased amounts of blue-violet light that my be dangerous. Why?

  • Blue light is all around  us. It is emitted by the sun and artificial light sources, including      digital screens such as your  smartphone, tablet, computer, etc. 
  • Blue light may be beneficial to our eyes in moderation as it is necessary for regulation of      the sleep/wake cycles, mood and cognitive performances.
  • But blue light can also be the cause of premature eye ageing. Overexposure to blue-violet light  can damage the retina and potentially increase the risk of age-related macular degeneration.


We are spending more time on digital devices and this can result in visual fatigue. Eyezen™ Start lenses have a new technology to digitally optimise the whole lens surface for both far and near objects. This helps to reduce visual fatigue through better visual comfort, better contrast and better clarity. A blue-violet light filter is a standard feature.
