3D Technology and Vision
Today, 3-D movie, TV and video games are rapidly coming on the market. Experts, like Avatar director James Cameron, predict all visual entertainment will soon be 3-D. Yet, there are some people who literally can’t stomach the 3D technology and find they have visual problems when viewing it. It has raised questions and concerns for both the public and product makers and you will most likely be seeing news stories about this topic (if you haven’t already). Some of the side effects for people viewing 3-D images are headaches, eyestrain, or motion sickness. Ophthalmologists are currently working to help the public understand:
- How the eye views 3-D images, and how this differs from normal, everyday depth perception,
- Why 3-D causes visual discomfort or headaches for some, and
- What impact this technology may have on vision
Some product makers are considering putting advisory labels on their products warning consumers to consult with eye doctors before buying. Samsung recently included a multi-point health warning with its newly-shipped 3-D TVs. People born with a lazy eye (amblyopia), or crossed eyes (strabismus) may not get the 3-D effect, unless the condition was corrected early, best before age 1. Some people whose eyes have a tendency to turn in or out, (expophoria or esophoria), have to work harder to fuse the images and they may feel more strain, and possibly headaches. Stay tuned for more information to come about 3D technology and how it interacts with our visual system.
