In daily life, many of us have experienced "blurred vision," especially when there is strong wind, it is easy to squint. At this time, many people are used to rubbing their eyes with their hands. Do we realize that this action can cause great harm to our eyes?
One, the reasons for blurred vision
Common causes of "blurred vision" include: sand, dust, small insects, coal slag, etc. falling into the eyes; debris from industrial accidents, explosions, or bursting of thermos bottles, or metal particles splashed by grinding wheels entering the eyes; glue spraying into the eyes; metal debris splashing or chemical substances such as lime flying into the eyes when engaged in electrical welding, grinding wheels, and outdoor construction operations, etc.
Statistics show that a large part of the causes of corneal inflammation are due to human factors. This is because our hands come into contact with many things every day, which are contaminated with countless bacteria and viruses. If we rub our eyes with our hands, these pathogens on our hands will contaminate our eyes and cause inflammation.
Two, do not rub your eyes when they are blurred
If we compare our eyes to a small camera, then the cornea on the surface of the eyeball is like a layer of glass in front of the lens, crystal clear but also extremely vulnerable to damage. When there is dust in the eyes, it will feel painful and difficult to open the eyes. However, rubbing with hands at this time will not only alleviate the pain but also cause the originally smooth cornea to be marked with angular sand grains and dust, making the eyes feel even more blurred and uncomfortable. If the cornea is severely damaged, it can cause corneal inflammation.
Three, how to deal with blurred vision
Therefore, when encountering dusty weather, even if the dust blurs the eyes, do not rub them with your hands. The best way is to close your eyes, slightly lower your head, because the eyes will produce a large amount of tears after being stimulated by the dust, and then blink, the dust will be flushed out with the tears. If this method does not work, you can ask someone to wash their hands and turn over the eyelids, gently stick or wipe away the dust with a clean towel or cotton ball, or flush away the dust with cool boiled water. If it is still impossible to remove foreign objects or if foreign objects are found on the cornea, go to the hospital immediately to have them removed. Avoid enlarging the wound or causing infection due to improper methods.
If you know the weather conditions in advance, you can take some protective measures, such as wearing a mask and protective goggles, using a veil to cover your head and face, tightening your cuffs, trouser legs, and collar, and immediately bathing and rinsing your mouth with clean water after returning home. Use a damp towel or gauze to protect your eyes and mouth when outdoor activities are required due to occupational needs.
