My eyes feel something foreign. What's going on?

The eyes feel foreign body sensation, which may be caused by the presence of foreign body residues in the eyes, exposure of the conjunctiva to the outside world, vulnerability to pathogenic microorganisms, or various stimulating factors. Cornea is the most sensitive area of human body, with abundant nerve endings. Various stimuli on eye surface will cause foreign body sensation, such as conjunctivitis, keratitis, blepharitis, eyelid trichiasis, conjunctival calculus, dry eye disease, etc. after eye trauma. If eyes show obvious foreign body sensation, go to hospital ophthalmology department for routine examination in time. If it is diagnosed as conjunctival sac foreign body or corneal foreign body, it is necessary to remove the foreign body in time and treat it with antibiotic eye drops to prevent secondary infection. If it is caused by conjunctivitis, it is necessary to treat it with antibiotic eye drops. Keratitis is caused by anti-inflammatory and needs to be treated with gel that promotes corneal epithelial hyperplasia.
