Samsung Electronics has posted an advisory on its corporate web site warning that children and teenagers may be more susceptible to health issues when viewing 3D content on their televisions.
The company also recommends that pregnant woman, the elderly and anyone under the influence of alcohol should refrain from watching programming in 3D.
Samsung also says that wearing 3D glasses for any other purpose may be physically harmful and could weaken your eyesight.
Negative reactions to 3DTV is not uncommon, especially among children and the elderly. Many movie goers reported experiencing dizziness, shakiness and headaches after watching 3D movies such as Avatar and Monsters vs. Aliens when they were released last year.
James Sutton, an optometrist explains: “The problem is that 3D offers a completely unnatural situation. It forces the eyes to work extremely hard. For many people, especially children, it causes eye strain, headaches and dizziness. Watching a busy action film, you can get what feels like motion sickness.”
The warning is especially noteworthy for parents since many of the slated 3D releases in the coming year are marketed towards young children and teens.
The following is the complete text of the Samsung warning.
