Computers, tablets, e-readers, smartphones and other electronic devices with visual displays all can cause tired eyes, digital eye strain and computer vision syndrome.
And computer-related eye problems have become widespread: according to a 2017 survey by The Vision Council, 72 percent of Indian adults reported having symptoms of digital eye strain.
Learn how to protect yourself from digital eye strain, including how specially designed computer glasses can relieve tired eyes, how computer ergonomics can minimize your risk of computer vision problems.
Computer Ergonomics For Healthy Vision
It seems nearly everyone in this digital world is spending a lot of time in front of a computer, which can strain the eyes as well as other parts of the body.
And anyone who uses a computer for prolonged periods — whether on the job, at school or at home for enjoyment — is at risk for headaches, burning eyes, red eyes, a stiff neck and other symptoms that comprise computer vision syndrome (CVS). Prolonged computer work also can cause physical stress that eventually could lead to a disability.
Here's the good news: You can reduce computer-related discomfort by becoming more aware of your body during computer work and adjusting your workstation and viewing habits to avoid these problems. The key is something called computer ergonomics.
What Is "Computer Ergonomics"?
Ergonomics is the science of designing a job, equipment and/or workplace to fit the worker. The goal is to optimize the "fit" between each worker and his or her work environment to optimize performance and reduce the risk of repetitive strain injuries.
Computer ergonomics addresses ways to optimize your computer workstation to reduce the specific risks of computer vision syndrome (CVS), neck and back pain, carpal tunnel syndrome and other disorders affecting the muscles, spine and joints.
Some experts in this field also use the term "visual ergonomics" when talking about designing a computer workstation with the goal of preventing CVS.
