The 3DS is Nintendo's latest version of its dual-screen portable gaming system. One of the screens is innovative because it allows the gamer to see 3-D without the use of special glasses. Although, the company warns against children below the age of six from playing with the game, optometrists say that the 3D screen helps identify vision problems such as amblyopia (lazy eye) and strabismus (eye turn).
If a child is unable to see the 3D effect, it can indicate that a problem exists with the way the eyes move, which eye charts don't tell you. That is why the Nintendo 3DS is approved by optometrists.
Nevertheless, Dr. David Hunter, a Pediatric Ophthalmologist at Children's Hospital Boston, has protested that while there is no concrete proof that 3-D games or movies can pose any major damage to the vision, the possibility is high that children can suffer from eye fatigue. He also states that his small son suffers from motion sickness after watching 3-D games or movies.
Jim Sheedy of Pacific University has been very practical when he says that that the health issue associated with console and computer gaming is obesity, rather than eye problems.
