Night lenses
You can see without glasses or contact lenses!
While you sleep at night, night lenses correct your vision and, when you wake up in the morning, you can see clearly throughout the day.
Night lenses provide comfort and safety in the usual daily activities, active sports, and free time!
Corneal refractive therapy is also called a method of vision correction with orthokeratology lenses. The technique is widely known as night lenses.
The method is based on changes in the cornea's shape using a unique lens at night when the patient is asleep.
The result is a temporary improvement in vision that lasts for about a day. So these lenses should be worn every night.
The unique lens creates a precise and suitable for each patient indentation in the cornea during the night. In the morning, after removing the lens, changes in the cornea allow the beam of light to focus on the retina's correct point, providing the patient with adequate visual acuity.
Night lenses are intended for people with low to moderate myopia (up to -6.00 diopters) with or without astigmatism (up to -1.75 diopters).
To determine the patient's suitability or non-compliance with the use of night lenses, a specialist consultation is required, during which the anatomical parameters of each patient's eye are evaluated.
Frequently asked questions about night lenses:
Is there an age limit for using night lenses?
There is no age limit.
- It is considered that night lenses can be used as soon as the child is responsible enough to put contact lenses in the eyes and take care of their hygiene, either independently or with parental involvement.
- The use of night lenses can be an excellent option for children and teenagers who are actively involved in sports or other activities that require good eyesight without glasses or contact lenses.
- Night lenses are also suitable for adults and seniors who, for various reasons, do not want or should not use other types of vision correction.
How long does it take to achieve good vision with night lenses?
Most patients have a rapid improvement in vision during the first days of treatment.
In almost all patients, visual acuity stabilizes entirely within 10 to 14 days.
When starting to use night lenses, it should be taken into account that initially, especially in the first days, visual acuity improvement may be shorter and last only a few hours. When the lenses are used with each passing night, the effect lasts longer and longer during the day until a more lasting effect is finally achieved.
There are also cases in which patients maintain visual acuity for up to three days after using the lens overnight.
However, in children and adolescents whose eyes are still growing, night lenses should be worn every night for maximum treatment, even though vision persists for several days.
Are night lenses difficult to insert and remove from the eyes?
Night lenses are no harder to insert or remove than any other contact lens.
Night lens users have access to a variety of aids, such as moisturizing drops that improve the mobility of the lens in the eye and make it easier to insert and remove the lens and a special lens removal aid.
Is it possible to see through night lenses if I wake up during a night's sleep?
Night lenses are designed so that you can see through them.
One of the great features of night lenses is that when you wake up in the middle of the night, the patient can move freely and see everything around you.
Is wearing night lenses painful?
Using night lenses does not cause pain.
The use of night lenses is not painful and physical changes in the cornea are not noticeable; only visual improvement is evident.
How to care for night lenses?
Night lens care is very simple.
Getting up in the morning:
- night lenses must be placed in the storage container provided for them;
- the container must be filled with a special peroxide liquid;
- a special disinfectant tablet is placed in a container with night lenses and peroxide solution;
- shake everything thoroughly to begin the disinfection process.
During the day, the lenses are cleaned and disinfected with the help of liquid so that in the evening, the patient can safely put them back in the eyes.
How often do I need to replace night lenses?
The manufacturer specifies
The lifespan of night lenses with proper and appropriate care is one year.
There may be situations where it is necessary to replace the lens sooner, such as an inappropriate shot, scratching, disappearance, and patients can also purchase a separate lens.
Can night lenses also be used on patients with signs of dry eye syndrome?
Generally, patients with signs of dry eye syndrome can wear night lenses.
Before using night lenses, it is necessary to consult a specialist; only an ophthalmologist or optometrist can determine a particular patient's suitability for night lenses.
Generally, patients with signs and symptoms of dry eye syndrome can wear night lenses and not experience any discomfort.
Because night lenses are used during sleep, tear evaporation is reduced, so in patients with dry eye syndrome, vision correction with night lenses may be particularly suitable.
Are there any risks associated with using night lenses?
The use of night lenses is associated with minimal risks.
Suppose a decision has been made to use night lenses. In that case, it is necessary to take into account a regular visit to a specialist - at first more often, later less often. The need for such visits is determined to monitor the correct positioning of the lens in the eye and the correction made at night.
Suppose the specialist is visited in order. In that case, the only thing that remains for the patient is to observe proper daily lens care and the necessary hygiene conditions to avoid the risk of infections.
If the patient follows all the instructions of the specialist, the risks are excluded.
