Causes of Corneal Foreign Bodies

Corneal foreign bodies are mainly caused by explosive droplets, broken grain shells, metal debris, etc. The specific analysis is as follows:

1. Explosive droplets

If the patient accidentally explodes in daily life, the explosive droplets will be embedded into the cornea at a faster speed, causing corneal foreign bodies.

2. Broken grain shells

If the patient is in the process of harvesting grain, the broken grain shells splash into the eyes, which will cause corneal foreign bodies, causing eye pain, redness, etc.

3. metal debris

If the patient is working in the factory, the metal debris is accidentally knocked over, causing debris to enter the eyes, which will cause corneal foreign bodies.
