What are the best conditions for TV viewing?
A normally lit room, suitable for general activities, is best. Excessively bright lighting tends to reduce contrast on the screen and “wash out” the picture. No lights should be placed where glare or reflections will be seen in or near the television screen. Strongly colored lighting should not be used and surroundings should be neutral in color.
Is it all right to watch television in a dark room? This situation is not ideal. When the room is totally dark, the contrast between the television screen and the surrounding area is too great for comfortable and efficient vision. When the room is softly illuminated, undesirable high contrast is kept to a minimum.
Is it better to adjust the television set to room lighting or room lighting to the set? Adapt the set’s brightness and contrast to room lighting — not room lighting to the set — after the room lights have been turned on.
Is it all right to wear sunglasses while watching television? Generally, no. Sunglasses may shut out too much light for good vision. If worn when not needed, they tend to make it difficult for the viewer to adapt promptly to normal light levels. If you are bothered by brightness, consult with an eye care practitioner about the possible need for lenses more appropriate to TV viewing.
