How to Tackle Computer Vision Syndrome

The productivity of a workplace depends on the well being of the people working there. Similar to the harsh working conditions found in areas dealing with chemicals and furnaces, offices using computers too come under high risk areas, due to the harmful effect of computers on the human body. Computer Vision Syndrome (CVS) is the name given to the injurious effects caused by over usage or improper usage of computers. Being a sensible and conscientious employer requires that you consider the overall health of the employees and see to that they are all well looked after and are in good working condition.

Computer vision syndrome is characterized by ocular or physical distress or a combination of both symptoms. There are two ways of approach to get rid of the computer vision syndrome. One is by changing the working style of the employees and the other way is to bring about a change in the working area that is the physical layout of the area is modified. We will see about the second method initially.
Adjusting the humidity:

The common complaints given by CVS victims are dry and itchy eyes. This can be relieved to some extent by adjusting the air flow in the room such that the air is not too cold or too hot and the direction of the flow can also be adjusted so that it does not fall directly on their faces.

Office lighting:
It's generally common for people working in an office to feel the strain of working for long hours. With the computer added to this situation, the troubles become doubled with increased strain to the eye and severe headaches becoming commonplace. To tackle this you have to use indirect lighting or lights that are toned down. Make sure the windows are adequately covered to prevent glaring and the colors used should have reduced reflective power. The use of a lighted keyboard alleviates the stress on eyes during night time use.
Use proper window coverings:

The monitors are prone to unwanted reflective power which makes it quite difficult for you to get on with your work. The windows should be covered with suitable anti glare screens and attachable file holders should be used for easier reading. The brightness level of the computer monitor and the color setting should be toned down to prevent CVS. A monitor full of dust and dirt will further compound the problem. Ensure that the system is kept clean and tidy.

Body posture:
Care should be taken while designing the workstation. The design should accommodate the human body and make the individual comfortable while working. Screens should be about 4-8 inches from the eye level and the top of the text should be at a 15 degree angulation below eye level. Chair design should be comfortable and easy to sit. The table should have ample space for legs below and at the top, for wrist and elbows.

Workers should be made aware of the effects of CVS and take proper precautions. They should be advised to take regular breaks from the hectic work schedule to give rest to their eyes.
