Wearing 3D glasses can cause headaches or migranes.
More and more current movies are being released on Blu-Ray in 3D, giving you a whole new perspective when watching films in your living room. Sales of 3D TVs are steadily increasing and are poised to reach 10 million by 2012, according to the "New York Post." With this increase in 3D TV sales, more Blu-Ray movies in 3D are bound to hit the market in upcoming years.
Pro: A New Viewing Experience
The primary advantage of watching 3D Blu-Ray movies is the novelty of being able to see the image in three dimensions. Although there is some debate as to whether this is an actual improvement in quality, more and more films are being released in this format. Another benefit is that you can watch these movies from the comfort of your living room instead of having to travel to a theater. For action films like "Tron: Legacy" and "Avatar," adding the 3D element brings the entertainment experience to a whole new level. The 3D effect is created by rearranging the color spectrum to present a stereoscopic image, which gives the illusion of depth. Two separate images of the same scene are superimposed onto the same screen. These images look out of phase and blurry to the naked eye. The color filters in the polarized lenses of 3D glasses bring the light and colors from these images together to form a three-dimensional image as you watch.
Con: Cost
The cost of Blu-Ray 3D players and movies has dropped in recent years, but is still more than Blu-Ray 2D players and movies. As of 2011, a 3D Blu-ray player costs about $400 and 3D glasses run about $80 to $100 per pair. A 2D Blu-Ray player costs $200 to $300 and no special glasses are needed. The price of a 3D television has recently dropped to under $1,000, but is still higher than an equivalent 2D television of the same size.
Con: Glasses
Special 3D glasses must be worn when watching 3D Blu-Ray movies on current 3D TVs. This restriction can be inconvenient. In addition, watching movies in 3D can cause headaches, migraines, astigmatism or lazy eye, according to "Cinema Spy." To enjoy the full 3D effect, you must sit directly in front of the TV, otherwise the images will appear blurry. The 3D images cannot be viewed from a wide angle.
Cons: Not Enough Content
Even though 3D is growing in popularity, there is a limited amount of 3D content currently on the market according to "LED TV." Relatively few movies have been filmed in the format, most TV channels are not broadcast in 3D, and NetFlix and other online movie providers do not yet stream 3D movies. In addition, most current Blu-Ray players are not capable of streaming 3D movies off such services at this time.
