Suffering from Computer Vision Syndrome? Here Are Some Exercises for You

Causes and Symptoms of Computer Vision Syndrome

Computer vision syndrome is caused by using a computer for a prolonged period. It usually affects people who sit at a computer daily for more than two hours.

Some of the symptoms include red eyes, dry eyes, headaches, blurry vision, eye discomfort, eye strain, pain in the eyes, shoulder and neck pain, and difficulty focusing. Some causes are computer glare, inadequate and improper lighting, hyperopia, astigmatism, improper sitting posture, and short viewing distance. Aging is also a factor.

Alleviating Symptoms with Proper Equipment

Usually, this condition resolves on its own. Relief is often felt when computer use is stopped, but in some cases, symptoms persist. Special computer glasses may be prescribed to alleviate symptoms. LCD screens are known to reduce eye strain, so it is advised not to use CRT monitors. The computer monitor should be 60 cm away from the eyes, and proper lighting should be used. It is also recommended to minimize glare on the screen. Customized lenses can also reduce this syndrome. A special instrument called a colorimeter is used to assess this condition.

Simple Eye Exercises to Reduce Symptoms

Symptoms can also be reduced by following some simple eye exercises. They are easy to do and do not require special instruments. One should try to blink more frequently while using a computer. Tears start evaporating if we don't blink regularly. Some people may have trouble focusing if they sit at a computer for a long time. To avoid this, they should follow the 20-20-20 rule: try to focus on something 20 feet away for 20 seconds every 20 minutes. This will significantly reduce eye strain.
