Is it normal to get headache and eyestrain after watching a 3D movie at home on a Samung 3D TV set?

It is possible. Many 3D systems, both passive and active can create headaches and eyestrain after extended viewing. Many viewers who are prone to motion sickness may also feel naseus depending upon the material being watched. No 3D systems are recommended for children under the age of 6 when using the 3D mode.
