When to seek medical advice

Get emergency medical care if you have sudden changes in vision or an injury to your eye. Specific factors that may accompany urgent vision-related medical conditions include sudden onset of:

  • Severe eye pain or irritation
  • Vision loss or double vision
  • Eye floaters, flashes of light or halos around lights
  • Severe headache
  • Nausea or vomiting
  • Numbness or weakness on one side of the body
  • Confusion, dizziness or trouble talking

See a specialist in vision problems (optometrist or ophthalmologist) if you experience any vision problems that impair your ability to read or write comfortably, drive safely, or participate in everyday activities.
