Both have side effects. If it is used to relieve visual fatigue and there are no other diseases in the eyes, Leton has obvious effect, but there are too many chemical components. Long-term use is not very good. If you are old, have a serious illness, have symptoms of dry eye, have eye drops dripping from live animals' eyeballs, and don't know the specific name of the biological preparation, you can go to the pharmacy for consultation. Moisturizing is generally possible, but it is easy to lead to an increase in intraocular pressure. Abuse of eye drops A variety of eye drops is one of the most commonly used drug formulations for the treatment of ophthalmic diseases. For many eye diseases, eye drops have a direct and rapid therapeutic effect. However, many people have no eye diseases, and they are used to taking eye drops frequently, or taking eye drops without being diagnosed with eye discomfort. Experts remind that this is all inappropriate, and the abuse of eye drops has many disadvantages. According to Professor Sun He from Clinical Medical College of Heilongjiang University of Traditional Chinese Medicine, most eye drops contain not only therapeutic ingredients, but also antiseptic ingredients. If eye drops are often dropped, the bactericidal components will destroy the ocular surface structure and produce irritating symptoms. Antibiotic eye drops are widely used, including bacterial infection, viral infection, fungal infection and chlamydia infection. This kind of eye drops should be used according to the course of treatment under the guidance of a doctor. If antibiotics are used blindly for a long time, drug-resistant strains will be produced. Many friends around me, since they knew that there were eye drops that could relieve fatigue, began to rely on those small potions and became essential items every day. Get some sand on windy days, refresh yourself when you are tired from work, and gradually develop the habit of chasing the wind with your eyes and using a little eye drops casually. Some patients with itchy and dry eyes (mostly chronic conjunctivitis) can't be recovered by casually ordering "eye drops", especially those with "video terminal syndrome" among urban white-collar workers. In order to relieve eye discomfort or fatigue, it is not good to buy some healthy eye drops and use them for a long time without the guidance of a doctor. At present, most eye drops contain preservatives. Long-term use will not only damage corneal epithelium, but also seriously damage conjunctival goblet cells, leading to dry eye. At the same time, long-term use of antibiotic eye drops may lead to the disorder of flora in normal conjunctival sac, leading to bacterial infection that is not pathogenic under normal circumstances, that is, conditional pathogenic infection. More seriously, it is also worth noting that long-term use of hormone eye drops may lead to "corticosteroid glaucoma". This type of glaucoma is often not easy to be found in time, and it is diagnosed as glaucoma at a later stage. The visual impairment caused by glaucoma is irreversible. Some patients are blind due to long-term use of hormone eye drops, which has attracted the attention of ophthalmologists. The doctor reminded everyone not to underestimate "eye drops". Whether the drug choice is correct is very important for eye health. The use of eye drops should follow the doctor's advice to avoid problems caused by improper medication. Traditional Chinese medicine claims that most eye drops that people use every day can cause allergies and drug resistance contain antibiotics (such as chloramphenicol), and such drugs cannot be used for a long time. If used every day, these drugs will first cause some side effects, but also cause allergies and drug resistance. In addition, some anti-fatigue eye drops have the effect of contracting blood vessels. It is best to consult a doctor before using it, and it is not recommended to use it every day. Chinese and western medicine * * * same suggestion: 1. It is best to listen to the doctor's advice for minor ailments. Ophthalmologists do not advocate that patients can choose and use ophthalmic drugs at will according to advertisements or instructions without seeing a doctor. Even if you need to prepare medicine at home or take medicine for a long time because of chronic eye diseases, you should not go to the ophthalmology consultation regularly and get the guidance of a doctor. 2. The application method of eye drops should be correct. Before taking the medicine, check whether the name, concentration and expiration date of the drug used are consistent with the packaging, whether the eye drops are turbid or flocculent, and whether they are discolored. Wash your hands before taking medicine, and don't let the bottle mouth of eye drops touch eyelids and eyelashes when taking medicine; Avoid dropping eye drops directly on the cornea (black eyeball); Those who need medication for both eyes should follow the order of healthy eyes first and sick eyes later; If both eyes are sick, you should be light before heavy.
