Night lenses Paragon.
Paragon CRT are therapeutic contact lenses that temporarily change the curvature of the corneal surface while you sleep. The effect obtained as a result of refractive therapy, when you remove the lens, is similar to the result of laser correction - a flattening of the central part of the cornea, therefore, a weakening of the refractive power. This allows nearsighted people to see clearly without glasses or soft contact lenses.
The difference is that the effect of refractive therapy is temporary. If you stop wearing Paragon CRT lenses, then after a few days (72-76 hours) the cornea restores its previous shape and the original vision returns.
The method of corneal refractive therapy using Paragon CRT after 3 years of clinical trials was certified in 2002 in the USA (FDA approval) and in the countries of the united Europe (CE).
The safety of using Paragon CRT contact lenses in children from 6 years of age has been proven by clinical studies.
Corneal refractive therapy is a non-surgical method of correcting vision by changing the curvature and refractive power of the cornea. Refractive therapy, or orthokeratology, has more than a century of history, when specially shaped lenses were first used to temporarily change the refractive power of the cornea.
How to wear Paragon night lenses
1. Do not overwear! The term of wearing Paragon lenses is up to 1 year. Even if they look like new, there may be damage not visible to the eye. If cracks or scratches are found on the lenses during wearing, they must be replaced immediately.
2. Follow the rules for lens care. After removal, put the contact lens in a special solution. The solution should be changed every time. You can consult an ophthalmologist about a solution for hard contact lenses.
3. Do not allow strangers to use
4. Observe the timing of sleep in orthokeratological lenses. Night action time 8-9 hours. You don't need to wear lenses during the day. If you sleep in lenses for less than 7 hours, 100% effect may not be achieved.
5. Reapply to the ophthalmologist's appointment. Should see a doctor at the end of the first week of lens wear and then every three months
Consequences of wearing contact lenses incorrectly
- Conjunctivitis. It develops due to excess sleep in night lenses. If you regularly sleep in the lens for more than 10 hours, then the cornea receives less oxygen.
- Microbial keratitis. May occur as a result of particles of cosmetics, dirt from unwashed hands, microdamages when touching the cornea with long nails on the ortholens
- Scar tissue. Occurs as a result of overwearing the ortholens
When is an ortholens used?
1. Myopia (nearsightedness)
2. Hypermetropia (farsightedness)
4. Progressive myopia in children and adolescents.
Contraindications for use
- Age less than 6 years
- Inflammatory diseases of the organs of vision
- Flu drank ARVI
- Cataracts, glaucoma, or some eyelid diseases
- Degenerative changes in the cornea
- Insufficient functioning of the lacrimal glands
Benefits of Paragon Night Lenses
- good vision throughout the day without the use of glasses or soft contact lenses
- Benefits in all sports
- slowing down or stopping the progression of myopia
- the risks that exist when using laser vision correction are excluded
- suitable for those who do not wash to wear soft contact lenses with dry eye syndrome
- well tolerated as they are made of hypoallergenic material and have a high gas tightness
- you can work in a profession where good vision is needed (pilot, driver)
- recommended for children aged 6 and up, plus improved results in lessons and sports training
Disadvantages of Paragon Night Lenses
- high cost compared to soft contact lenses
- discomfort may be felt in the first days of wearing
Tips for wearing night lenses
- Lenses must be applied regularly - every night
- if wearing at night does not improve vision, there may be several reasons: the right and left lenses are reversed, the lenses are not properly worn and shift during sleep
- if corrective therapy is prescribed for a child, then parents should control the process.
