Outlook

Recovery depends on the type and extent of injury.

• Chemical irritants seldom cause permanent damage.
  
  
• Recovery from acid and alkali burns depends on the depth of the injury.

The 4 grades of burns are

• Grade 1: You should recover fully.
  
  
• Grade 2: You may have some scarring, but your vision should recover.
   
• Grade 3: Your vision will usually be impaired to some degree.
  
  
• Grade 4: Damage to your vision likely will be severe.
