用VR療法,幫孩童治療弱視 VR headset can help treat amblyopia in children

About 3 percent of children suffer from amblyopia, which is the leading cause of vision problems in children. In traditional treatment methods, patients are asked to block the stronger eye with a patch, forcing the brain to rely on the weaker eye.

A technology company launched a virtual reality-based treatment. Patients watch a movie through a headset that displays images to each eye separately. The images shown to the stronger eye have lower contrast and are presented in a superimposed manner, forcing the brain to use both eyes to see the images correctly.

The study shows that 62% of the children using the therapy had a significant improvement in their vision. However, only 33% of children in the comparison group showed similar improvements.

 

友善讓你懂|解說:

 
約有3%兒童患有弱視,這也是導致孩童視力問題的主因。傳統療法中,通常會要求患者用貼片遮住視力較佳的眼睛,迫使大腦去使用較弱的眼睛。

不過,一家科技公司推出VR新療法。患者用頭戴顯示器看電影時,頭顯會分別向兩隻眼睛呈現影像。視力較佳的那隻眼睛看到的影像對比度較低,並會以疊加的方式來呈現,讓大腦不得不用兩隻眼睛來正確觀看。

研究發現,採用新療法的孩童中有62%視力明顯改善;而對照組孩童中,僅有33%有出現類似改善。

 

輕鬆帶著走|學習:

 
comparison group指的是實驗中的「對照組」,control group則指「控制組」。

 
例句:​​
Those in the comparison group did not show any differences.
對照組裡頭的受試者沒有顯現出任何差異。
