To watch 3D videos, you usually need to wear 3D glasses,
and for people like me who already wear glasses, adding another layer of 3D glasses can be particularly uncomfortable.
Being able to watch without such discomfort is a significant advantage.
This video you watching is actual Da Vinci Robotic surgery footage.
As a surgeon, even though I see it in three dimensions, the assistants can only view it in two dimensions.
In 2D, understanding anatomy can often be challenging.
However, I feel like seeing it in 3D stereoscopically would lead to faster comprehension.
