Steven Nusinowitz, an associate professor of ophthalmology at the Jules Stein Eye Institute in Los Angeles, says 3D glasses have a polarized filter that separate two images, thereby enabling the 3D effect. But the doctor adds that the separation occurs so quickly that your brain may have difficulty accepting it.

He estimates that about 20 percent of viewers will get sick when watching 3D. Additionally, Samsung recently posed a medical caution about watching 3D TV at one of its web sites.

“We’ve long believed that 3DTV faced a tough road with numerous obstacles, namely content availability, consumer interest and viable business models,” said Strategy Analytics' Ben Piper, according to Home Media. “However, these issues all take a back seat in light of the latest findings.”
