Using a VDT for long periods can cause visual fatigue and eye strain. Symptoms of visual fatigue are eye irritation, burning or pain, blurring of vision, and double images. Preventive measures can be taken to ensure correct vision for this type of work.

The National Institute for Occupational Safety and Health (NIOSH) recommends that employees have periodic eye examinations. The vision care benefits available in your employee benefits program may be used for this purpose.
Eye exams should be performed by a licensed optometrist or ophthalmologist who is familiar with the visual demands of VDT work.
Contact lens wearers should blink often to avoid the eyes from becoming dry.
Frequent eye breaks are necessary during the day.
Occasionally focus on an object at least 20 feet away to give your eyes a rest.
