Despite what our mothers told us as children, sitting too close to the TV is not harmful to your vision.

According to the Canadian Association of Optometrists (CAO), sitting too close to the TV does not cause permanent damage to your eyes. Instead, it causes eye strain and fatigue.

Eye strain and fatigue can be a problem because it means that your eyes are tired, which translates into blurred vision. The remedy is to rest your eyes, and your vision will return to normal.

While sitting too close to the TV can lead to eye strain and fatigue, watching TV in the wrong lighting can cause even more unnecessary eye strain. The CAO recommends watching TV in a well-lit room to prevent this unnecessary strain on your eyes.
