What is Eye Strain?

Sore, Dry, Tired Eyes, Headaches are all common Symptoms

Eye Strain today is an epidemic.  Is it any wonder, with the amount of time we spend sitting in front of computers, televisions and hand held games?  Whoever designed the human eye never designed it for doing close activities for hours on end and that is where eye strain comes in.  Eye strain is simple to treat and even avoid, therefore it is a problem that no one should have to endure!  A day does not go by that Jim Kokkinakis Optometrist, The Eye Practice Sydney CBD, does not see cases of eye strain that are caused by today’s excessive visual demands.

Eye strain is a form of eye discomfort which occurs when you overuse your eye muscles.  Any muscle held in one position for too long will strain.  When concentrating on tasks such as reading, working at the computer or watching television for prolonged periods of time, your inner eye muscles tighten up causing various symptoms including eye irritation, dryness and discomfort.

Another commonly used term related to eye strain is Computer Vision Syndrome. Computer Vision Syndrome is the combination of eye strain and body muscle strain that is experienced during or related to computer use.  In most cases, symptoms occur because the visual demands of the task exceed the visual abilities of the individual to comfortably perform the task.

If Eye strain or Computer Vision Syndrome are not diagnosed and treated correctly they can have a direct effect your well-being and productivity.  Not to mention wrinkles from having to squint to see clearly!
