How to apply eye drops 1. Wash your hands; 2. Check the eye drops; 3. Unscrew the lid of the eye drops and place the lid correctly to avoid contamination; 4. Take a sitting or supine position with your head slightly tilted back and your eyes looking upward. Next, gently poke the lower eyelid downward with the index and middle fingers of one hand, hold the bottle in the other hand, put 1D2 drops into the eyelid, and then gently lift the lower eyelid upward to fully distribute the solution in the conjunctival sac; 5. Gently close the eye after the drops and press the inner corner of the eye with the index finger for 2D3 minutes (if the child is very uncooperative, do not force it). Explanation: 1.The dropper should be 2~4cm away from the eye to avoid touching the eyelashes, contaminating the dropper or touching the eyeball. 2, do not put eye drops directly on the cornea (black eye), because the cornea is sensitive to cause reflexive eye closure and squeeze out the eye medication. 3, the tear sac is located in the inner corner of the eye, if not pressed in time, eye drops will soon flow from this into the tear duct, and subsequently into the nasal cavity. In this way, one is the short time that the drops stay on the surface of the eye, the effect of the drug is not sufficient; secondly, the tear sac and the nasal cavity are rich in blood vessels, the drops can be absorbed into the blood, increasing the side effects of eye drugs and even causing danger. This is especially true if the patient has a combination of heart disease and lung disease. Therefore, holding the inner corner of the eye in time to prevent the drops from entering the tear sac soon increases the contact time between the drops and the eye, improves the efficacy of the drops, and also prevents the drops from flowing into the tear sac and nasal cavity via the tear duct, reducing side effects. 4, such as the simultaneous use of more than two kinds of eye drops, drops should be more than 10 minutes after the interval, and then another kind of medicine. 5, expired eye drops can not be used. Eye drops should not be stored together with other drops, such as foot drops, to avoid accidentally pointing into the eyes.
