Dry eye drops are not as good as blinking

Abstract: it is normal for the eyes to work overload for a long time. In order to alleviate the dryness of the eyes, many people drop eye drops. In fact, regular eye drops are bad for the eyes. If the eyes are dry, it’s better to blink more.

carries a bottle of eye drops with them and drops them from time to time, which has become the eye protection method of many white-collar workers. However, the efficacy of eye drops varies. If they are not used properly, they may have adverse effects on the eyes. Recently, doctors in the ophthalmology clinic received several patients with dry eye and drug-induced corneal conjunctivitis due to long-term random eye drops.

people stare at the computer screen for a long time, blink less, can not secrete tears, form a tear film to protect the cornea, and lack of lubrication in the eyes leads to dryness. Most eye drops with moisturizing effect publicized in the market do not have the effect of treating dry eye disease. They not only do not have the function of lubrication, but also have side effects.

why do people with dry eyes often use anti fatigue eye drops, which are effective at the beginning, and then feel more and more uncomfortable? This is because eye drops may contain preservatives. At present, no eye drops can prevent eye diseases. Therefore, to protect the eyes, the most important thing to pay attention to is to use the eyes scientifically and combine work and rest. Others use antibiotic eye drops or hormone eye drops as soon as they feel eye discomfort. However, these eye drops will cause eye flora imbalance, may induce non pathogenic keratitis and conjunctivitis, and are easy to produce systemic drug resistance.

at present, there are three types of eye drops on the market. One is antibiotics, which mainly treat eye infections. Long-term abuse may lead to imbalance of eye flora. The second is artificial tears, which can moisturize the eyes and relieve dry eyes. The third is hormone eye drops, which are used to reduce and treat dry eyes, allergies and other problems, but long-term use may cause optic nerve damage.

studies have shown that the probability of dry eyes in Chinese is higher than that in Westerners. Due to the long time that urban white-collar workers face fluorescent screens such as computers or televisions, dry eyes are becoming a common ophthalmic disease. At present, there are at least 100 million dry eye patients in China, and dry eye has accounted for 20% ~ 25% of the total number of ophthalmic clinics in China.

so how should dry eyes be prevented? One way of

and

is to reduce the time facing the fluorescent screen and blink more when tired. In addition, appropriate supplementation of deep-sea fish oil or vitamins may help. Contact lens wearers should try to avoid using eye drops containing preservatives, because most preservatives will be absorbed in the lens, and long-term use will cause damage to the cornea. It is recommended that contact lens wearers try to use eye drops without preservatives.
