1. When do you usually order eye drops? 17% at any time of the day 2. Before going to bed 17%3. Eye discomfort
67%. Expert comment: Generally, it is best to close your eyes for a few minutes after dropping eye drops, which is beneficial to absorption. Eye drops are better after getting up early, before taking a nap and before going to bed at night. At other times, you should pay attention to choosing eye drops when you have plenty of time. Don't eat them all at once, and do something else at once.
2, a few drops of eye drops at a time. 1) decline17%; 2) Two reductions of 50%; 3. Not sure 33%. Expert comment: 1 ~ 2 drops of eye drops once is enough. Too many drops can not only be absorbed, but also may cause adverse reactions. A drop of eye drops is about 30 microliters, but the storage in conjunctival sac is usually only 7 microliters. If more eye drops are dropped, the capacity of conjunctival sac can only be increased to 30 microliters at most, and the excess eye drops either overflow from the corner of the eye or flow to the nasal cavity along the nasolacrimal duct. For those eye drops that have no toxic side effects and stimulating effects, a few more drops are just a waste.
3. The basis for choosing eye drops. 1) Composition of eye drops 10%2. Advertising 7%3. The doctor suggested 30%4. Pharmacy staff recommended 3%5. The experience of oneself or friends accounts for 50%. Expert comment: Although many eye drops can be selected by yourself, it is best to ask an ophthalmologist to check them before buying them, and then buy them according to the doctor's advice. If you must choose, you must read the instructions carefully. If you feel uncomfortable during use, seek medical advice immediately.
4. Some eye drops can't be dropped indiscriminately. Many people order eye drops because others introduced them, especially when their symptoms are "the same" as others. In fact, it is very dangerous to do so. There are several kinds of eye drops that need special attention. Firstly, atropine eye drops are used to treat acute iridocyclitis. The main symptoms are redness, pain and decreased vision. Atropine can dilate pupils, diminish inflammation and prevent iris and lens from adhering. Because of its strong mydriasis effect and long action time, it usually takes about three weeks to fully recover after mydriasis. During this period, it is difficult to shrink it with drugs, so improper use of 1 atropine eye drops may cause irreparable losses. Some patients mistakenly used atropine because of "jealousy" symptoms, leading to blindness. There are also some drugs for preventing and treating myopia that have similar effects to atropine (such as tropicamide eye drops commonly used by teenagers, with the trade name of "Shuangxingming"), which can treat pseudomyopia by dilating pupils and relieving spasm. Although this drug has a short action time and usually disappears after 8 hours, it can't be used casually. Hormone eye drops, such as cortisone acetate eye drops, should not be used indiscriminately. At first, these eye drops can effectively relieve dry eye and red eye, but long-term use will cause increased intraocular pressure, even optic nerve damage, visual field defect and vision loss, which will lead to corticosteroid glaucoma. Moreover, this kind of glaucoma has mild symptoms and slow course of disease, so it is difficult to find it in time in clinic. Eye drops are not "necessities". In principle, eye drops are not needed. As long as computer users do the following, they don't need to take eye drops regularly: don't use the computer for too long, insist on using the computer for 40 ~ 50 minutes, ensure that their eyes rest 10 ~ 15 minutes, look far away, let their eyes fully relax, and work in front of the computer for no more than 6 hours every day. People who wear contact lenses usually need to pay attention to personal hygiene, wear and remove them in strict accordance with normal operation procedures, and don't have to always order eye drops. In addition to eye drops, there are some ways to relieve dry eye: do eye exercises, wet and hot compress with hot towels, and look at the distance.
5. Use eye drops moderately. In order to maintain the sterility of drugs and extend the validity period of drugs, preservatives are usually added to ensure the quality. Although trace preservatives are harmless to eyes, repeated use of eye drops and long-term excessive exposure to preservatives may cause damage to eyes, resulting in damage to normal tear film and corneal epithelial cells. So in principle, don't use eye drops if you don't use them. If it must be used, it should not be used more than four times a day. 6. Be careful when mixing eye drops. When I bought eye drops, I saw that this eye drop has such a function, and that eye drop has such a function. Their complementary function seems to solve my own eye problems, so when I use eye drops, I mix them up and drop another one five minutes later. For this method, some eye drops can be mixed and some cannot be mixed. Some eye drops will reduce the curative effect after mixing, and some will even produce toxicity. Therefore, if you want to mix eye drops, you should seek the doctor's advice and don't take it for granted.
