Despite Nintendo's recent warning that children ages 6 and younger shouldn't play games in 3-D mode on the company's upcoming 3DS portable video game system, eye doctors say parents shouldn't be overly concerned that their kids' eyesight could be damaged by the toy."This is just a precaution by Nintendo," said Martin Banks, an optometry and vision science professor at University of California, Berkeley. "No one's shown anything that this is a direct concern for kids less than 6 years of age."Nintendo recently posted a warning on its Japanese website that playing games on the device might make some people feel sick, and could be dangerous to young children's developing vision. In an official statement from Nintendo of America, spokesman Charles Scibetta said, "Nintendo's position is children 6 and under should not use the 3-D feature of Nintendo 3DS, and parents should use the parental controls feature to restrict access to the 3-D mode."The video game device is set to be released by … [Read more...] about 3-D Video Games Unlikely to Damage Children’s Eyes

Major League Baseball had a serious hitting bubble in the late 1990s, as any fan probably knows, but what caused it has been an ongoing controversy that smells of steroids.Players had a collective batting average in the late '90s of .269, about 10 points higher than an earlier era from 1969 to 1973, according to figures collected by two University of Nebraska-Lincoln sports historians.Afterwards, from 2001 to 2006, the aggregate MLB batting average dropped to .265. Runs per game follows the same pattern, the historians state in a new report.Bursting the bubbleBenjamin G. Rader and Kenneth J. Winkle wanted to understand the hitting trends for the 1969 to 2006 seasons. The era following 1994–2000, which they call Baseball's Great Hitting Barrage of the 90s, has been the puzzling one. What cooled down the wild hitting bubble, with its home-run rallies and record-breaking performances?Was it drugs that pumped up those figures and then drug testing, which began in 2003 (although … [Read more...] about The Truth Behind Baseball’s Hitting Slump
Each week, MyHealthNewsDaily asks the experts to answer questions about your health. This week, we asked optometrists and ophthalmologists: What's the best way to preserve your eyesight? Here's what they said.Dr. Bala Ambati, associate professor of ophthalmology and visual sciences at the University of Utah and director of corneal research at the John A. Moran Eye Center:"When it comes to preserving your vision, early detection is key. Vision problems can often be prevented or delayed through early detection and treatment."Full visual exams every two years are sufficient for healthy adults in their mid-20s to mid-30s with the exception of those who wear contact lenses, in which case they should be seen each year. Routine exams are recommended for those in their late 30s and beyond because vision changes and eye diseases are more likely to develop. Anyone with a history of visual problems, diabetes, high blood pressure or lupus should get routine preventative care at least annually."If … [Read more...] about 5 Experts Answer: What’s the Best Way to Preserve My Eyesight?
Lazy eye, the most common cause of visual impairment in one eye among children and middle-aged adults, may be linked to a defect in how the brain detects motion, a new study suggests.Lazy eye, also known as amblyopia, is a condition that involves reduced vision in one eye because that eye and brain are not working together properly. The eye may look normal, but the brain favors the other eye, according to the National Eye Institute. The condition affects 2 percent to 3 percent of all children, and unless treated, will persist into adulthood.Previous research into the cause of lazy eye focused on visual processing in a part of the brain called the primary visual cortex. But while this research deepened scientists' understanding of the condition, it did not explain issues with motion perception, according to the researchers."This study shows that amblyopia results from changes in the brain that extend beyond the primary visual cortex," study researcher J. Anthony Movshon, director of the … [Read more...] about Lazy Eye Linked to Defects in Motion Detection
Have you ever wondered why your cat's eyes have those creepy vertical slits for pupils? A new study suggests the reason may lie in cats' preferred mode of hunting.Vertical-slit pupils are most common among nocturnal predators that ambush their prey, according to the new research, published today (Aug. 7) in the journal Science Advances. Most likely, this pupil shape provides the sharpest way to gauge distance for a prey-snatching leap, the study found.The new research doesn't only demystify the housecat, however; it also reveals that the bizarre horizontal, rectangular pupils sported by goats and sheep likely help these prey animals scan the horizon for predators — and watch the terrain when sprinting from danger. Moreover, circular pupils tend to be found on tall, active predators that are awake during the day. (Sound familiar, humans?)
