No, it is not bad for your eyes. If you use a pair of 3d glasses, it will not have any harm to your eyes. As we know, all 3d glasses do filter light. There are double images of everything. Some say that the other image will come through a bit that is meant for the other eye and cause problems. When I saw the movie up I would close one eye and try to see the other image come through but it absolutely does not come through. Actually it is good for the eyes because it causes you to exercise your eye muscles in a slightly different way, some people are just lazy and don't want to try something new. On the other hand, they could cause certain short-term effects for adults such as headaches and dizziness, but for children with developing eyes they can be a bit harmful to their vision. So if you have child, you should be careful about it.
