Is a condition that can often be neglected during a normal optometry consultation, its definition is: a temporary condition resulting from focusing the eyes on a computer screen for long periods of time. Some common symptoms include, head aches, blurred vision, neck pain, fatigue, eye strain, dry, irritated eyes and difficulty refocusing the eyes. These symptoms can be further aggravated by improper lighting conditions and air moving across the eyes.
Experts agree that a primary cause of dry eye and eye strain is the use of computers in the workplace. When we use computers we spend long periods of time using our eyes for near viewing. Additionally, the monitor has its own light, which is not reflected and we tend to stare at the screen, often without blinking enough, which in turn leads to dry eye.
Ergonomics of the office also play an important role in reducing eye fatigue. To reduce frequent head movements while sitting in front of the computer experts say that reference material should be placed as close as possible to the monitor and it is advisable to adjust the monitor screen brightness and contrast to a comfortable setting. Also it is essential that you have an anti-reflective coating on your lenses to minimise glare from monitor screens and overhead lights.
Glancing away from the monitor every 15min to focus in the distance also goes a long way to reducing eye fatigue.
To choose Anti-Reflective Coating within the Lens extras on the Right Hand Side of the order screen, can really help reduce the symptoms of fatigue. www.onlyspecs.com.au
