Abstract: the combination of contact lenses and charged substances in eye drops will lead to sediment on the lenses, resulting in discomfort. The mist like sediment will change the diopter of the lens and aggravate the myopia over time; Granular sediment can rub and even damage the cornea and cause keratitis.
with contact lens drops
contact lenses are often dry when they are worn for a long time. Some people will use eye drops to moisturize their eyes. The combination of
contact lenses and charged substances in eye drops will lead to sediment on the lenses, resulting in discomfort. The mist like sediment will change the diopter of the lens and aggravate the myopia over time; Granular sediment can rub and even damage the cornea and cause keratitis.
in addition, the adsorption of contact lenses will absorb the preservative components of eye drops and concentrate them to 25 ~ 30 times, causing damage to the eyeball.
contact lenses wear overdue
recently, a lyrics has been widely spread in the overtime dog industry: “I haven’t removed my makeup for 18 days, but I have worn it for two and a half years every month”. It can be seen that the phenomenon of overdue wearing of contact lenses is common.
our eyeballs secrete protein every day. Even if we use nursing solution every day, we can’t completely clean it. Contact lenses are easy to adhere to foreign bodies when worn over time, causing eye allergy, keratitis and even corneal ulcer; On the other hand, contact lenses will become airtight or even damaged, resulting in corneal hypoxia and edema.
wear glasses with mismatched degrees
some people believe that the more glasses are worn, the deeper the degree is, so they deliberately match the degree of glasses low, which is believed to control the growth of myopia.
however, wearing glasses with inappropriate degrees will not only cause blurred vision, dizziness and nausea, but also cause the continuous growth of eye axis and the deepening of myopia, or cause cryptostrabismus or strabismus.
directly clean the lens with detergent / paper towel
some friends directly wipe the lens with paper towel or detergent when cleaning the glasses. However, after we wear them all day, many tiny pollution particles will adhere to the lens, and direct friction with the lens will cause lens wear. The wear of
lenses will lead to the decrease of light transmittance and inaccurate degree. Wearing worn glasses for a long time will increase the degree of myopia and aggravate vision problems. The correct way of
is to wash with clean water first, then wash with neutral detergent, and finally wipe the lens directly with clean spectacle cloth or soft paper towel.
