Can sitting too close to the TV damage your eyes?

Many parents have cautioned their children about sitting too close to the TV, expressing concerns that it could harm their eyes. The belief was rooted in the idea that the proximity to the screen might strain the eyes or lead to vision problems.

This advice was especially prevalent during the era of cathode-ray tube (CRT) televisions, where concerns about radiation exposure were also raised. However, scientific evidence supporting the notion that sitting close to the TV damages eyesight is limited. Children can focus at close distance without eyestrain better than adults. Therefore children often develop the habit of holding reading materials close to their eyes or sitting right in front of the television.

The American Academy of Ophthalmology states that sitting close to the TV is unlikely to cause permanent damage, but it may lead to temporary eye strain. When a child sits close to the TV, this could be a warning sign that the child has developed strabismus, a problem with eye alignment, or that the child may need glasses for nearsightedness or farsightedness.

Modern televisions, such as LCDs and LEDs, emit negligible radiation compared to older CRT models. While the advice to sit farther away from the TV may have been well-intentioned, it is essential to consider advancements in technology and the lack of substantial evidence supporting the claim. As with any health-related advice, consulting with healthcare professionals is recommended.
