Foreign objects entering the eye occur frequently in daily life. Many people's first instinct is to rub their eyes or resort to folk remedies—like having someone blow into their eye to dislodge the object. Experts do not recommend either approach, as improper handling can further damage local eye tissues. Below, we outline the correct steps for removing foreign objects from the eye.
Foreign Objects in the Eye: Incorrect Handling Makes Things Worse
Many everyday situations can lead to foreign objects entering the eye, such as accidental eye injuries from fireworks during the New Year celebrations, or exposure to dust, small insects, debris, and so on. Generally, smaller foreign objects will first attach to the cornea.When discomfort or pain occurs, people instinctively rub their eyes. However, rubbing rarely removes the foreign body effectively. Worse, it can dislodge the particle from the corneal surface, causing scratches or even penetrating deeper into the corneal stroma, leading to irreversible damage. Additionally, rubbing transfers bacteria from the hands to the eye, potentially causing infections and inflammation.
Sha Xiangyin advises that if the corneal epithelial damage is not severe, it will gradually heal within a few hours. However, if the sensation of a foreign body persists, even without significant discomfort, a medical examination is necessary. Prolonged presence of the foreign body can cause ulcers, perforations, or even scarring on the cornea, which may impair vision.
Different foreign objects require different treatments
Different foreign objects entering the eye cause varying degrees of damage. Therefore, first-aid methods also differ.
For common foreign objects like dust, the eye naturally produces tears to flush them out. Blinking appropriately can increase tear flow. If ineffective, eye drops may help dislodge the object.However, the eye drops used must be sterile and uncontaminated. Avoid using eye drops that have been opened for over a month or those that may become contaminated during use due to close contact with the eye.
Injuries caused by accidental exposure to fireworks are considered complex injuries. Avoid excessive handling and seek immediate medical attention. It is recommended to cover the injured eye with clean, sterile gauze to provide protection and prevent further infection.
Chemical injuries to the eye, such as acid or alkali burns, are also common in daily life. If not treated promptly, such foreign objects can easily cause blindness. Dr. Sha Xiangyin emphasizes that chemical eye injuries require immediate flushing with the nearest available water source—tap water, bottled water, or even pond water if clean water is unavailable.If the chemical substance inside the eye isn't flushed out promptly, it can cause further damage. The next step is to seek treatment at a reputable hospital as soon as possible.
Additionally, when a foreign object causes severe damage to the eye, such as a laceration, immediate consultation with an ophthalmologist at a reputable hospital is essential. If the eye is lacerated, besides pain, there will be noticeable fluid leaking from the eye.Under no circumstances should you rub the eye, rinse it, or cause any vigorous disturbance like excessive blinking. Keep your face facing upward to minimize pressure on the eyeball. The above outlines the dangers of rubbing your eyes after a foreign object enters them. We hope you remember these precautions.
