“Sitting too close to the TV damages your eyes.”

The notion that sitting too close to the television will permanently damage your eyes is a persistent misconception with roots in a genuine, albeit temporary, historical issue. This myth largely originated in the late 1960s when a specific batch of General Electric (GE) color television sets was found to emit excessive levels of X-ray radiation due to a manufacturing defect. These faulty sets emitted radiation significantly higher than what was considered safe, leading to a public health scare and a recall of the televisions. Even before this incident, some televisions manufactured before the 1950s also emitted levels of radiation that could heighten the risk of eye problems with prolonged exposure.

However, modern television technology has rendered this concern obsolete. Today's flat-panel televisions, including LCD, LED, and OLED models, operate very differently from the old cathode-ray tube (CRT) sets and emit negligible amounts of radiation, posing no risk of permanent eye damage. While prolonged close viewing can still lead to temporary discomforts like eye strain, headaches, or fatigue, these symptoms are not indicative of lasting harm to your vision and typically resolve with rest. The American Academy of Ophthalmology confirms there is no evidence that sitting too close to a TV causes permanent damage to either children's or adults' eyes.

The enduring belief in this myth stems from the initial radiation scare of the 1960s, which, combined with widespread anxieties about technology and radiation during the Cold War era, deeply embedded the warning into parental guidance. Furthermore, the temporary eye strain or discomfort that can arise from focusing intensely on a close screen naturally makes people feel as though they are causing harm, reinforcing the long-held misconception. Children, in particular, often sit closer to screens because their eyes can focus at short distances more easily than adults' eyes, a habit that usually diminishes with age.
