symotoms & Causes
Symptoms of eyestrain and dry eyes result from exposure of the eyes to dry air or when air movement is fast inside the office. Tears evaporate easily under these conditions. Also, if the room is dusty, the particles may enter the eyes making the symptoms of eye strain worse. Exposure to cold draught decreases blood circulation and leads to slight tensing of the muscles in the affected area. Acute discomfort is felt usually in the neck, shoulders and back.

Improvement Plan
@
Set the room temperature to 24-27 degrees Celsius during summer and to 20-23 degrees Celsius during winter. Maintain relative humidity of 40-70%.
Optimum air velocity is 0.1 m/sec or less. If you are troubled by strong air coming from the air conditioner, you can use a partition to redirect flow of air.
A humidifier may help increase relative humidity in your workstation.
Maintain good ventilation in the room and do regularly housekeeping. Promote a smoke-free work environment.
Make sure that you discuss these measures with your co-workers before changing anything. Remember that changes in the general work environment will likely affect the people around you.
