When the eyes are short-sighted, many people wear contact lenses in order not to affect the appearance. Everyone should be very familiar with contact lenses, but recently I found that some people still have some misunderstandings about contact lenses.
I saw a friend post a few days ago:
"Oops, I can't find my contact lenses! Did it fall into my eyes? Will it cause damage to my eyes? What should I do? Wait online!"
I could feel her nervousness across the screen, so I commented below Moments:
Don't scare yourself, contact lenses will not fall into your eyes! It may be that the contact lens has fallen off, so look around carefully.
After more than ten minutes, I received a private message from her: She found a contact lens that had fallen in a corner of her desk...
Although this incident ended without any danger, many people who have worn contact lenses for many years do not know some knowledge about contact lenses.
Can contact lenses fall into the eyes?
The conjunctiva of the human eye (a soft, smooth and transparent film covering the upper and lower eyelids and the surface of the eyeball) is actually a closed structure. After wearing the contact lens, it is only on the surface of the eye and cannot slip into the eye. go.
If you really have contact lenses suddenly disappeared, there are two possibilities at this time:
- The glasses have fallen out when you are not paying attention.
- If it remains on the eye surface, you should go to the hospital for examination in time, and the doctor will take out the contact lens.
Will wearing contact lenses damage my eyes?
Because the human eyeglasses will secrete tears, which exist between the cornea and the contact lens to act as a barrier, so the contact lens will not directly contact the eyeball, let alone cause damage to the eye.
However, people with dry eyes need to pay special attention, because the tear secretion of their eyes is relatively poor, and insufficient tear fluid may indeed cause contact lenses to rub the eyes and cause infection. Therefore, it is not recommended to wear contact lenses for patients with severe dry eye.
What are the precautions for wearing contact lenses?
Since the lens needs to be in contact with the eye surface, you must be careful when wearing it, and you also need to know some precautions about wearing contact lenses.
People who are not suitable for wearing contact lenses:
Patients with frequently inflamed eyes, dry eyes, corneal injuries, or other eye conditions are not suitable for wearing contact lenses.
When to wear:
The more scientific and reasonable way to wear contact lenses is: wear them when necessary, such as when studying and working; and if it is a rest time, try not to wear them if you can.
How long to wear at a time:
Generally, contact lenses should not be worn for more than 8 hours during the day, and should not be worn overnight. Wearing contact lenses for too long can easily lead to visual fatigue, dry eyes, and blurred vision.
So, if you are not used to wearing contact lenses, and you are short-sighted, you should get a pair of glasses early, what, it is very expensive, then you must not know koalaeye.
