What not to do after an eye injury

An eye injury is a medical emergency. The first few minutes after an accident are critical. While your instinct might be to help, many common first-aid reactions can cause permanent damage or blindness. Knowing exactly what actions to avoid is just as important as knowing what to do. Below is a guide to the most dangerous mistakes and the science behind why they are harmful.

Why rubbing the eye is dangerous after an injury

Rubbing is the most common and dangerous reaction. If a foreign object, such as metal, glass, or dirt, is embedded in the eye, rubbing can drive it deeper into the cornea or sclera. This increases the risk of a corneal laceration, which requires surgical repair. Furthermore, if the eye has a hidden rupture, rubbing can force the internal contents of the eye (vitreous humor, retina) out through the wound, leading to irreversible vision loss.

Should you apply pressure to a bleeding eye?

No. Never apply direct pressure to the eyeball itself. If the eye is bleeding, it likely indicates a penetrating injury or a ruptured globe. Applying pressure raises intraocular pressure and can expel the internal structures. Instead, if there is bleeding around the eye (from the brow or cheek), you can apply gentle pressure to the bone surrounding the socket, but keep the pad away from the eyelid margins.

Can you wash an eye with water after a chemical burn?

Yes, but only for chemical burns. However, the most common mistake is using the wrong type of water or technique. Do not use “eye wash” cups that recycle the contaminated water. Do not use milk, juice, or any homemade solution. The correct protocol is to flush with lukewarm tap water or sterile saline for at least 15-20 minutes, holding the eyelid open. For alkali burns (like drain cleaner or lye), flushing must continue for 30-60 minutes while en route to the hospital.

Is it safe to remove a foreign object from the eye?

No, never attempt to remove an object that is embedded in the eye. This includes metal shards, splinters, or glass. Removing it can cause the eye to deflate (hypotony) or create a tract for infection to enter the deep eye. Only a specialist using a slit lamp and proper instrumentation should remove embedded objects. If the object is large (like a knife or pencil), stabilize it in place with a paper cup or shield and go to the ER.

Common mistakes after an eye injury

• Using cotton swabs or tweezers to touch the eye surface.
• Applying ointments or eye drops before a doctor has examined the injury (they can mask symptoms or cause chemical reactions).
• Patting the eye with a rough cloth or tissue.
• Closing the eye tightly if a rupture is suspected (this increases pressure).
• Taking aspirin or ibuprofen for pain (these thin the blood and increase bleeding).
• Waiting to see if symptoms improve before seeking help.

Emergency checklist: What to do instead

• Stay calm and do not touch the eye.
• If a chemical injury: flush with water immediately for 20+ minutes.
• If a blunt injury (e.g., punch): apply a cold compress to the eyelid (not the eye) to reduce swelling.
• If a sharp object is stuck: do not remove it. Place a paper cup over the eye to protect it.
• Cover the uninjured eye to limit movement of the injured eye (both eyes move together).
• Go to an emergency room or call an ophthalmologist immediately.
