many women who love beauty like to wear contact lenses. Even many girls who are not short-sighted will wear beautiful pupils without degrees, making their eyes look & ldquo; Bright and moving & rdquo;. However, wearing contact lenses will increase the risk of eye infection, and may also affect vision, such as corneal deformation, blurred vision, diplopia, refractive changes (such as uncorrectable astigmatism). Therefore, be extra careful. Let’s take a look with you.
In three cases, do not wear contact lenses
1. It is not suitable to wear
during menstruation. This is because the intraocular pressure of women is higher than usual during menstruation, and it is easier to congest around their eyeballs, especially for women with dysmenorrhea. At this time, wearing contact lenses will have an adverse effect on the eyes. In addition, the immunity of women during menstruation decreases, the resistance of eye clear also decreases, and the secretion of tears decreases, which may deposit the metabolites of bacteria between the cornea and contact lenses, and there is a risk of bacterial corneal ulcer.
2. You can’t wear
when your eyes are not in time. You can’t use contact lenses when you suffer from upper blepharitis, wheat granuloma, eyelid inverted eyelashes, dacryocystitis, insufficient tear secretion, dry eyes, conjunctivitis, trachoma, keratitis, glaucoma, scleritis, iridocyclitis, etc.
3. Not everyone can wear
. Before wearing, go to the hospital for detailed ophthalmic examination. After routine examination, medical optometry, measurement of corneal curvature radius and corneal fluorescein staining should also be done.
note: the contact lens soaking solution should be replaced every two days.
different brands and types of nursing solutions must not be replaced or mixed, nor should they be cleaned with detergent, salt water or tap water. When cleaning the lens, rub it with clean hands for more than 30 seconds to achieve the cleaning effect. Contact lenses cannot be soaked in liquid medicine for a long time. They usually need to be replaced in two days to avoid breeding bacteria. Also pay attention to replacing new contact lenses and storage boxes.
The harm of wearing contact lenses for a long time
1, the decline of eye resistance
contact lenses will prevent the cornea from contacting the air, and the eyes will be similar to the human body due to hypoxia & ldquo; Altitude sickness & rdquo; Can not metabolize normally and the resistance decreases.
2. Cause visual fatigue and dry eye
wearing contact lenses for a long time is easy to produce visual fatigue and even dry eye. Lead to itchy eyes, foreign body sensation, multiple eye excrement, dry sensation, burning eyes and blurred vision.
3. Cause eye allergy
contact lenses adsorb proteins, lipids and collagen in tears to deposit on the lens surface, breed bacteria, corneal edema, corneal neovascularization reaction and allergic reaction.
4. Wearing cornea and unable to be corrected
contact lenses wear cornea, which may cause serious consequences of corneal epithelial abscission or perforation. The concavity of some contact lenses is inconsistent with the corneal convexity. They wear the cornea irregularly, causing corneal ulcer and irreversible visual loss. Even after treatment, white spots will be left on the cornea.
5. Cause eye paralysis
contact lenses attached to the eyeball for a long time will paralyze nerve endings and lead to decreased corneal perception. Many patients are unaware of ulcerative keratitis.
Five key points of matching
1. Wear strictly.
standardize the operation of wearing and taking off contact lenses according to the training regulations of the wearer and the instructions to prevent nails, clips and sharp objects from damaging the lenses.
.
of the specialists are examined by professional ophthalmologists. They are suffering from trachoma, keratitis, conjunctivitis, hypertension, diabetes, endocrine disorders and other minor diseases.
3. Generally, the first wearer will go to the wearing Center for inspection after one week.
the regular wearer will recheck once every three to six months. If any inapplicable problem is found after use, he should go to the wearing Center for inspection at any time to ensure eye hygiene.
4. Strictly prevent chemical damage
contact lens wearers using cosmetics must follow the principle of wearing glasses before makeup, and taking off glasses before removing makeup, so as to strictly prevent the lens from being damaged by shampoo, skin care and beauty chemicals.
5. Storage safety and hygiene
lenses shall be removed and put into a special lens box and immersed in nursing solution. The lens box shall ensure disinfection and hygiene and prevent the lens cover from crushing the lens.
Precautions for cleaning contact lenses:
1. When cleaning the lens, first drop the contact lens solution on the lens, and gently rub both sides of the lens with your index finger up and down for 10 seconds. Do not touch the lens with your fingernails.
2. Rinse the lens with contact lens liquid medicine. Please follow the instructions and instructions on the liquid medicine package. After washing, put the contact lens in the cleaned lens box, and the lens must be completely soaked in the liquid medicine.
3. The service life of contact lens care solution after bottle opening is generally 3-6 months, depending on different care solutions.
4. The mirror box needs to be washed every day and disinfected once a week. The mirror box can not be replaced for more than 3 months.
