When it's windy, it's easy to narrow our eyes. At this time, many people are used to rubbing their eyes with their hands. Do we realize that this action can cause significant damage to our eyes?
According to statistics, a large part of the cause of keratitis is 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 can contaminate our eyes and cause inflammation.
If we compare our eyes to a small camera, then the cornea on the surface of the eyeball is like the glass in front of the lens, clear and transparent, but also extremely vulnerable to damage. If dust enters the eyes and attaches to the cornea, it will cause pain and difficulty in opening the eyes. However, rubbing the eyes at this time not only does not alleviate the pain, but also causes the originally smooth cornea to be scratched by sharp sand grains and dust, resulting in blurred vision and discomfort. If the cornea is severely damaged, it can lead to keratitis.
Therefore, in dusty weather, even if our eyes are irritated by dust, we should not rub them. The best way is to close our eyes and lower our head slightly, because the eyes will produce a large amount of tears after being irritated by dust, and blinking will wash away the dust along with the tears from the corners of the eyes.
If this method doesn't work, you can ask someone to wash their hands and flip your eyelids, and then gently remove or wipe away the dust with a clean towel or cotton ball, or rinse it out with cool boiled water. If it is still not possible to remove foreign objects or if foreign objects are found on the cornea, you should immediately go to the hospital to have a doctor remove them. Avoid enlarging or infecting the wound due to improper methods.
If we know the weather conditions in advance, we can take some protective measures, such as wearing masks and protective goggles, covering our head and face with a veil, fastening cuffs, pant legs, and collars, taking a shower immediately after returning home, rinsing our mouth with clean water, and using a damp cotton swab to clean the nasal cavity. If it is necessary to work outdoors due to occupation, it is best to protect the eyes and mouth with a wet towel or gauze.
A friendly reminder from the editor:
With the popularity of contact lenses, the market is flooded with various types and brands of glasses. Here, experts remind us not to just focus on the brand when buying contact lenses, as they not only differ in brands but also have different applicable ranges. Our eyes are crucial to us, so we must choose contact lenses that are suitable for us. Experts believe that different brands of contact lenses have different focuses in design and different characteristics in materials. Different degrees of astigmatism should be matched with different brands of lenses. Therefore, the choice of contact lenses should be determined by a professional optometrist based on each person's situation.
