Dispensing eye drops is one of the main treatments for eye diseases. It seems to be simple and easy, but the percentage of people who can correctly regulate and scientifically use the medicine is extremely low. If the method of operation is not standardized or wrong, it will produce adverse eye reactions, such as eye cross-infection, eye damage, eye drops are contaminated and wasted and other adverse consequences, so scientific standardization of drug administration is very important. Now the correct method of eye spotting is introduced as follows: you can lie down or sit with your head tilted back and your eyes looking upward, after cleaning your hands, pull the lower eyelid downward, the mouth of the eye medicine bottle is 2-3cm from the eye, and put 1 drop into it. After the drop, gently press the part between the inner corner of the eye and the root of the nose for 2 to 3 minutes. Caution: 1. Clean your hands before using the medicine. If the color of the eye drops has changed or has expired, do not use it anymore. 2. When using medication in both eyes, point to the healthy eye first and then to the affected eye. 3. Do not put drops directly on the cornea (black eye) when ordering the medication. 4. The mouth of the bottle should be at least 2 to 3 cm from the eyelid when using the medicine. 5. If you use more than two kinds of eye drops at the same time, you should take 5 to 10 minutes after using the medicine before using another kind of medicine.
