Samsung warns of potential health risks of 3D TVs

Children, pregnant women and the elderly are named as being susceptible to potential health risks.

Samsung has issued a warning on the potential health risks of 3D television technology for certain categories of users.

The TV maker issued guidelines warning of nausea, dizziness and cramps or involuntary movements such as eye or muscle twitching, especially in epileptics.

Consumers are advised to take breaks and avoid watching movies or playing games in 3D when they're "in bad physical condition, need sleep or have been drinking alcohol," they said.

Children are more at risk than adults, and parents have been asked to supervise them closely. Pregnant women and the elderly are also noted as being susceptible to possible health hazards from the technology.

3D television technology renders only an approximation of the real three-dimensional view that human eyes naturally have, which could lead to fatigue, says a report citing an ophthalmologist at the Harvard Medical School.
