A fingernail eye scratch is a corneal abrasion caused when a nail scrapes the clear front surface of the eye. This injury exposes sensitive nerves and causes sharp pain, tearing, and light sensitivity. Vision may blur temporarily. These scratches are common in children, contact lens wearers, and accidental hand-to-eye contact. Most heal with proper care.
read more about fingernail eye scratch ...Abrasion occurs when a fingernail catches the cornea during rubbing, play, or sudden movement. Long nails increase risk. Contact lenses can worsen the injury if worn after the scratch. Foreign particles on the nail surface also add to damage.
People describe the following symptoms.
Doctors apply dye to highlight the abrasion under blue light. They check the eyelid for trapped debris that could cause repeat injury. Vision testing helps rule out deeper damage. The pattern of staining shows the size and depth.
Treatment includes lubricating drops, antibiotic ointment, and avoidance of contact lenses. Pain control may be needed for comfort. Most scratches heal within one to three days. Follow-up is recommended for larger injuries.
Most are minor and heal quickly.
No. Contacts can slow healing and worsen irritation.
Infection is possible if debris enters the wound.
Seek help if pain worsens, vision drops, or symptoms do not improve.
