In most cases, if you have continuing symptoms of pain, visual disturbance, or bleeding, you should go to your eye care professional.
Continuing pain and decreased vision after an eye injury can be warning signs that require prompt medical attention. If you have an optometrist, he or she may be able to take care of you in the office. Otherwise, go to a hospital's emergency department.
Chemical exposures: If the substance was known to be caustic, immediate medical evaluation by either an Optometrist or in the emergency department is needed, regardless of symptoms. Acids and alkalis are the worst and require immediate attention. If the substance is not dangerous, such as soap or suntan lotion, a visit to the emergency department is not necessary, but a visit to the optometrist's office may be helpful to alleviate any remaining symptoms. When in doubt, seek medical attention.
