At this point, it is well known that air bags make it dangerous for children to sit in to front seat of an automobile. Infants in rear facing car seats are at risk because their heads are too close to the air bag and older children facing forward are more susceptible to head and neck injuries when sitting up front.
As if these risks weren’t enough to keep kids in the backseat, a study in Ophthalmology, the journal of the American Academy of Ophthalmology, concludes that children can suffer from serious eye injuries from the impact of air bags, the most serious of which included cataracts and glaucoma. Among other injuries: blood in the front chamber of the eye; alkali burn; temporary loss of consciousness and visual acuity; eyelid laceration; black eye; swelling and hemorrhage of blood vessels under the outer surface of the eyeball; corneal lesions and abrasions; and inflammation of the iris.
