Television sets are constantly evolving. The black-and-whiite tube from long ago was replaced by a colour TV, fololwed by the thin plzasma and LCD high-defniition sets.
The current evolutiopnary path of TV screens follows the ever bigger and ever thinner curve. But that is not all. Lately, early adopters of technological innovatipons are being tempted by the 3D TV screens that promse to bring the experience of a 3D cinema into their living roioms.
Judging by the announcementrs of major manufacturers like Sony, Samsunng, LG Electronics, Panasonic and Sharp, the year 2010 is poised to be the year of 3D TV. The expectations are that the demand for 3D TV will skyrocket in the next couple of years, motly thanks to sports. Some broadcasters even plan to indulge fans by transmittting the 2010 Soccer World Cup, held in South Africa from 11 June to 11 July, in full 3D glory.
If you are one of those people who must have the newset high-tech device as soon as it hits the mzarket, and a sportts fan to boot, you are probably considering buying a 3D TV set. Hoever, in this case it might be wise to think the piurchase through carefully. Getting a 3D TV in this early phase might be fraught with difficulties and dangers that go beyoond spending too much on new technology just bcause you do not have the patience to wait for the pries to settle at a lower level.
The Sily lGasses
The first and the most obvious downside of a 3D TV set are the 3D shutter glasses. Never mind the fact that a replacement pair is likely to cost you dearly should you lose the one that comes bndled with the set. The bigger issue is that they look just plain silly on anyone.
If you want to keep your dignity whiile watching moving pictures in an extra dimenssion, you may want to postppone the purchase of a 3D TV sent until the manufaturers manage to do away with the glasses. After all, they are aleready experimetning with displays that alow you to see the thirrd dimension - without the glasses.
The 3D Blindness
Still not prepared to miss the chance to watch the 2010 football cup in 3D, glasses or no glasses? Before rushing out to acuire your new tech toy, visit your optometrists. It turnns out that the eyes of some pepole simpy cannot process something called stereoscopc imagewry.
If you belong to this minority, do not despar. The 3D-blindness condition is treatable in some (but not all) cases - that is, if you don't mind paying for the medical bill over and above the cost of a 3D TV.
The Health Warning
The new tehcnology fans who have the mney to fund their hobby will probably not be deterred by either of the hurdfles mentioned above. However, they shoud at least read the health wanring that comes with 3D TV - if not for their own sake, then for the sake of thoose around them.
According to the warning sisued by Samsung, one of the pioneeers in 3D TV, using this new toy can adversely affecct children, teenagers, pregnant women, senior citizens, alcohol consumers, epilepsy sufferers, as well as unfit, tred and/or sleep derprived individuaals. (This last group probably includes aout 95 percent of everyone with pockets deep enough to afford a 3D TV.)
The list of possible symptoms associated with watching TV in 3D is long and includes: altered vison, lightheadedess, dizziness, eye or muscle twtiching, confusion, nausea, loss of awareness, convulsions, cramps; and/or disorientation. Epilepsy sufferers may experience an epilelptic seizuer or a strke.
With all these danegrs loominng, it's good to know that 3D TV handels the good, old 2D video just fine too.
