Improper contact lens care may lead to conjunctivitis and keratitis
Contact lenses are transparent lenses made of polymer materials that are directly attached to the corneal surface to correct refractive errors. Therefore, as a contact lens, contact lenses must be scientifically fitted and properly cleaned, otherwise it is easy to cause many eye diseases, and in severe cases, keratitis and corneal ulcers can be induced and affect vision.
According to experts, many ophthalmic diseases such as conjunctivitis and keratitis may be related to improper care of contact lenses, and severe corneal ulcers may occur.
Nursing mistakes
Thinking that the care solution is "no rubbing", no care is needed for the lens, just remove the lens and put it in the care solution, which will cause protein precipitation on the surface of the lens and even the attachment of pathogenic microorganisms; think that as long as the lens is properly cared for It is enough, but neglects cleaning, disinfection, and replacement of the lens case containing the lenses; ignores the shelf life of the care solution, and does not regularly replace the care solution that is not used up after opening; ignores the use period of the lenses, and does not replace the lenses in time, causing protein Precipitation and microbial growth have an impact on visual clarity and even ocular complications.
Who are contact lenses suitable for?
Experts said that contact lenses are mainly suitable for people who need to wear contact lenses with aesthetic needs or special circumstances.
For example, people who have a large difference in the degree of their eyes, cannot wear frame glasses or are uncomfortable wearing frame glasses, and cannot undergo myopia correction surgery.
Generally speaking, myopic people aged 16-38 are most suitable for using contact lenses; middle-aged people aged 40-60 can wear them for a short period of time, because after the age of 40, the local resistance of the eye decreases, especially the ability of the eyeball to tolerate hypoxia It is best not to wear it for the elderly over 60 years old, because the secretion of tears in the eyes of middle-aged and elderly people decreases, and some people will develop dry eye syndrome, which can easily cause complications and permanently damage their vision. How should contact lenses be cared for and maintained?
The current contact lens care solution is mostly a three-in-one full-effect care solution of cleaning, disinfection and maintenance. In addition to cleaning and disinfecting the lenses according to the instructions, you should also pay attention to the cleaning of your hands, glasses case, and care solution.
Usually, hands should be washed before taking off and wearing lenses; the lens case should be washed with cleaning solution every day, disinfected every week, and replaced every 3 months; care should be taken not to contaminate the bottle mouth after opening the care solution; contact lenses should not be shared with others; required Makeup wearers should wear contact lenses before makeup and remove contact lenses before removing makeup to prevent cosmetic damage to the lenses; if the lenses are not worn for a long time, they must be thoroughly cleaned, rinsed, and disinfected, and then soaked in the care solution every 3 days. Change the care solution once.
For people of different ages, frame glasses also have a "shelf life"
Wearing "extended service" glasses for a long time will affect vision health to varying degrees, and for people of different ages, the "lifespan" of frame glasses also varies from person to person.
