Small particles, metal shavings, wood fragments, contact lens debris or a scratch to the eye surface can cause a foreign-body sensation and superficial corneal damage. Typical immediate effects are tearing, pain and a feeling that something is in the eye. Below are plain-language explanations of what these injuries are, safe first-aid measures, common evaluations, and when to see a specialist.
What it is and common causes
A corneal abrasion is a superficial scrape of the cornea’s outer epithelial layer. It can result from airborne particles, direct trauma, contact lens problems or chemical exposure. Working with metal, woodworking, gardening or any task that produces small high-velocity fragments increases the risk of a retained or embedded foreign body and secondary infection risk.
Symptoms and when to seek urgent care
Typical symptoms include a persistent foreign-body sensation, increased tearing, redness, light sensitivity, a scratchy pain and sometimes blurred vision. Seek urgent medical evaluation if you have sudden loss of vision, severe or worsening pain, visible bleeding, a suspected embedded object, or if the injury followed a significant facial or head trauma. In those cases, visit an emergency department or urgent care without delay.
Safe first-aid steps
Avoid rubbing the eye. If available and you can do so gently, rinse the eye with clean water or sterile saline to help wash out loose particles. Do not attempt to probe for or remove an object that appears embedded, and avoid using unsterile tools. For severe pain, suspected embedded material, or vision changes, seek professional assessment promptly.
Evaluation and which specialist to consult
Ophthalmology (eye specialists) evaluate corneal abrasions and ocular foreign bodies. An exam may include visual acuity testing, slit-lamp inspection and fluorescein staining to highlight corneal surface defects. If a deep injury or metallic foreign body is suspected, imaging studies such as X-ray or CT may be used. The eye specialist will advise on monitoring and next steps.
Prevention and workplace safety
The most effective prevention is appropriate eye protection: safety glasses, face shields or goggles when working with tools, metal, wood, chemicals or during yard work. Follow workplace safety guidelines and use proper contact lens hygiene. If an eye injury occurs at work, follow your employer’s emergency procedures and seek evaluation.
