A jellyfish or Portuguese man-of-war sting to the eye may be quite painful at first, but the pain will usually get better within 30 minutes and go away completely within 24 to 48 hours. You may have a feeling that something is in your eye (foreign body sensation), increased sensitivity to light (photophobia), or blurred or hazy vision.

A sting to the eye or eyelid may cause:

• Damage to the cornea.
• Inflammation to the colored part of the eye (iritis).
• Scratches or tears to other structures of the eye.
• Increased pressure within the eye (glaucoma).
• Rupture (perforation) of the eyeball.

Any sting to the eye or eyelid could lead to blindness or damaged eye function and must be carefully checked.
