Dhanraj Vishwanath from the University of St. Andrews in Scotland said that simply looking through a small hole is enough to experience 3-D, CNN reported.
Currently the 3-D technology that's used in movies and other media relies on two visual images, one from each eye, combining in the viewer's brain to produce 3-D's extra layer of depth, but the new research has suggested that both eyes aren't needed.
The researcher said in a statement that for the first time they have demonstrated experimentally that the same 'special way' in which depth is experienced in 3D movies can also be experienced by looking at a normal picture with one eye viewing through a small aperture.
Vishwanath said that preliminary results of their finds suggest that their method could be used to allow people with misaligned eyes to experience what it is like to actually see in 3D.
The study is published in the journal Psychological Science.
