Patients should close their eyes to stimulate the lacrimal glands to secrete tears, thus flushing out the foreign body slowly, usually for a few minutes to an hour or so. If, after the sand is flushed out with tears, the patient can still feel the foreign body when the eyes are closed, it is recommended to go to the hospital for ophthalmology treatment in a timely manner. For foreign bodies on the conjunctiva, patients can gently wipe them off with a cotton swab under a slit lamp, and foreign bodies on the cornea can be similarly removed. If eye drops are available, patients can put in artificial tears or antimicrobial eye drops to play a flushing role and help the foreign body to be discharged. In addition, patients should be careful not to rub their eyes or constantly flush their eyes with water to avoid damage and infection of the eye. If the above methods are not effective, it is recommended to go to the ophthalmology department of a regular hospital as soon as possible to remove the sand and other foreign bodies with the help of a specialist, without delay, so as not to aggravate the degree of eye injury.
