National statistics reveal that more than 1 million people in the U.S. are legally blind. Many of these people do have some ability of sight, but they require some measure of assistance to function. Almost 5 percent of those affected suffer vision loss because of some type of injury. The most frequent types of incidents are:
- Injury to the brain, scalp, skull
- Blunt force trauma to the eye by a foreign object
- Intracranial hemorrhages
- Laceration
- Chemical injuries
