眼睛干痒时如果经常揉,容易导致结膜炎症。医生根据症状,有时会开2~3个不同种类的眼药水。这里要提醒大家,眼药水可别滴多了。一滴眼药水通常大约50微升,人眼的结膜囊只能容下40微升。因此,每次点一滴就够了,多了浪费。如果需要用两种眼药,至少应间隔5分钟。有的需要间隔更长时间,如用于抗细菌(如治红眼病)的眼药 Eye dry itchy if often rub, easily lead to conjunctival inflammation. According to the doctor’s symptoms, sometimes open 2 to 3 different types of eye drops. Here to remind everyone, eye drops do not drip more. A drop of eye drops is usually about 50 microliters, the human eye conjunctiva can tolerate only 40 microliters. Therefore, a drop of each point is enough, more waste. If you need to use two kinds of eye drops, at least 5 minutes apart. Some require longer intervals, such as ophthalmic drugs for anti-bacterial (such as red-eye disease)
