If you are having trouble seeing in 3D
Before looking at the 3D films, try viewing these test images :
The red circle should appear farthest away and the yellow should appear
closer. If you cannot perceive the 3D effect, adjust your distance from the
screen.
.
Can you guess which object is closest?
Which way is the box pointing?
If you are still experiencing trouble seeing in 3D
You may belong to the 5% of people who are unable to see in 3D. If, using
any glasses, you cannot perceive the depth in these pictures or films, or if
you can see in 3D but only at the cost of eye strain or headache, you may be
suffering from vision problems.
Several ocular conditions can cause inability to perceive 3D (even if these
do not necessarily affect our daily lives), such as:
 | Amblyopic or lazy eye
| Strabismus
| Convergence insufficiency (difficulty maintaining clear
focus, especially at close range) |
