light source while watching tv

Question
I am wondering about watching TV with a light source. How much light is necessary while watching TV? My husband insists on having a bright overhead light while watching TV, but I believe having one or two table lamps on is enough to not cause any harm or strain on our eyes and or our children eyes while watching TV. Could you tell me how much light is enough?


Answer
Dear Janette,



The correct light is like that of a natural source, preferably tube lighting, not the yellow lighting.



Yes, the room should be well lit that the eyes do not see a contrast in the light source from the TV which would otherwise strain the eyes.



Dim light for TV can be occassional.



Hope this helps,

Best,
