【轉貼】 研究:兒童未滿6歲 別看3D

(法新社巴黎5日電) 「法國食品、環境及 職業衛生安全局」(ANSES)今天建議,6歲以下兒童不 應接觸3D電影、電腦和電動,6到13歲兒童接觸也應「 適量」。

衛生安全局說,這項建議所依據的,是1項「先驅 性的」科學研究,內容主要探討3D成像對發育中眼睛可 能帶來的危害。 衛生安全局提到,各種設備的3D技術爆炸,現在連 手機也有3D功能。 衛生安全局在聲明中建議,眼部還在發育的6歲以 下兒童,不要暴露到這些3D設備,13歲以下的兒童接觸 也應適量。 衛生安全局說,3D讓眼睛的「聚散-調適」( vergence-accommodation)功能被破壞。

所謂「聚散- 調適」,是指人的雙眼聚焦在1個物體上時,眼球所做 的調整。 當眼睛看螢幕上的3D圖像,眼球適應的過程是不一 樣的。 2隻眼睛必須同時看著圖像上2個不同的地方,直到 被大腦合為1個圖像。

聲明說:「在這種3D視覺系統積極發展的現今,兒 童接觸3D,尤其是6歲以下的兒童,這種聚散-調適所造 成的健康效應衝突恐特別嚴重。」(譯者:中央社李佩 珊)

French health watchdog warns on 3D usage for children

A French health watchdog has recommended that children under the age of six should not be allowed access to 3D content.

The Agency for Food, Environmental and Occupational Health and Safety (Anses) added that access for those up to the age of 13 should be "moderate".

It follows research into the possible impact of 3D imaging on still-developing eyes.

Few countries currently have guidelines about 3D usage.

According to Anses, the process of assimilating a three-dimensional effect requires the eyes to look at images in two different places at the same time before the brain translates it as one image.

"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," it said in a statement.
Nintendo warning

It is not the first time questions have been raised about the safety of 3D, which is used in many feature films as well as on some video games, TVs and computer screens.

Italy has sought to restrict the use of 3D glasses by young children, following a similar warning from its national health agency last year.

When Nintendo released its 3D video console in 2010 it warned that playing games on it could damage the eyesight of children under six.

More and more firms are creating 3D-enabled products and Apple is rumoured to be developing a 3D display that can be viewed without the need to wear special glasses.

The American Optometric Association has said that it has had no reports of eye damage as a a result of viewing 3D content.
