QUOTE said:The advent of 3D gaming has lead to questions whether the effect can lead to permanent eye damage.
Luckily for Nintendo, Sony and other companies, Los Angeles-based ophthalmologist Mark Borchert doesn't believe that 3D is likely to cause any significant problems.
"There are people who get uncomfortable with it, and get eye strain or headaches, or on much rarer occasions, a sense of imbalance or nausea, but there's no evidence it can cause permanent harm to your vision or use of both eyes together or anything like that," he told Gamasutra.
Nevertheless, Sony is being cautious. They recently updated the PlayStation Network's Terms of Service with an item titled "3D Device Use Notice," which advises users to consult a doctor before a young child to play 3D games.
Borchert does warn that 3D could have a negative impact on the eyesight of young gamers, though he doesn't believe it will be an immediate issue.
"[Binocularity and stereoscopic vision] is something that is learned in the first few years of life, primarily in about the first three years of life. So it's unlikely that children at that age, where stereoscopic vision is developing most critically, are going to be playing these games," he said.
Borchert admits that ophthalmologists have "no idea" what the impact of 3D will ultimately be on the eyesight of young children, but said he can't imagine it harming anyone over "four years of age."
Barring any further developments, sounds like we're in the clear.

There are some differences between Sony's and Nintendo's implementation of 3D, so who knows. But odds are the technology is safe but not recommended for over use.
