When sand enters the eye, it is recommended to rinse it out with plenty of water. If there is still discomfort such as a foreign body sensation after rinsing, it is recommended to go to a regular ophthalmologic medical institution in time to have it removed with tools or treated with medication. When sand enters the eye, you can use a large amount of water to rinse it out on the spot, turn the eyelid and rotate the eyeball when rinsing, and try to rinse out the sand as much as possible. If there is no discomfort after flushing, no further treatment is needed. If there is still discomfort, it is necessary to consult a clinician for appropriate treatment. If the sand is on the lid conjunctiva or bulbar conjunctiva, it can be wiped with a cotton swab. If the sand is on the cornea, it needs to be carefully removed with a needle after anesthesia has been applied and treated with infection-preventive eye drops, such as levofloxacin eye drops.
