“In the real world, to perceive depth and relief, the eyes converge (i.e. they are directed at the same object) and accommodate (the lens of each eye changes shape to obtain clear vision) at the same distance, i.e. the distance to the object being observed. The creation of artificial stereoscopic effects by technical means (3D) makes it impossible for the eye to respect this physiological principle.”
According to this report, children under 6-years of age should avoid watching 3D content as it could damage their still-developing eyes. ANSES also noted that children up to age of 13 should also limit their 3D viewing to avoid damaging their vision.
“In children, and particularly before the age of six, the health effects of this vergence-accommodation conflict could be much more severe given the active development of the visual system at this time.”

Even as adults, it can be very exhausting to sit through a movie watching it in 3D. Some people even notices visual fatigue, dry eyes and visual disorders after watching such a film. If you feel such symptoms, ANSES strongly recommends to limit your exposure to 3D content and consult an ophthalmologist, despite your age.
