Can VDTs cause eyestrain?
VDTs definitely are associated with eyestrain. One can notice a variety of symptoms from redness, watering, and irritation to fatigue and heaviness of the lids along with difficulty in focusing. Much of this is related to focusing at a single distance for a prolonged period of time while sitting at a VDT. Headaches, backaches, and muscle spasms can also occur and are related to the ergonomic positioning of the person at the VDT. Rearranging your work station and providing proper periodic breaks relieve many of these symptoms.
