There is a science to using eye drops properly, and the Ministry of Health and Welfare Food and Drug Administration invited a pharmacist to explain just how to do it. According to pharmacist Wu Wen-che, if you are using more than two different types of eye treatment at the same time the medication will not be absorbed as well as it could, and the order of application will also affect how efficiently it is absorbed. Wu says that you should wait at least 5 minutes between using each type of treatment, and recommends first using the solution, suspension (eye drops) and gel before applying ointment.

Wu also explained the correct method for using eye drops. You should either lean your head back or lie down on your back and look up, then tug your lower eyelid out a bit and apply the drops, according to the dose recommended by the manufacturer. Lightly close the eyes and roll your eyeballs, to allow the liquid to be distributed evenly over the cornea. You can also apply light pressure to the corner of the eye nearest the bridge of the nose, to prevent the liquid from flowing out of the tear duct. Avoid blinking too much or squeezing the eyes shut, as this might squeeze out some of the liquid, reducing the effectiveness of the treatment.

For the eye ointment, one should squeeze around 0.5 to 1cm of ointment inside the lower eyelid and then lightly shut the eye for between 1 to 3 minutes, again slowly rolling the eyeball. This might lead to blurred vision for a while, and so ideally it should be done before going to sleep.

In addition, eye medication should be stored in a cool, dark place. If the instructions indicate that it should be refrigerated, it should be placed in the refrigerator, not the freezer, and when taken out for use it can be warmed up first in the palm of the hand, so that it does not cause discomfort.(Translated by Paul Cooper)
