Wake up and see clearly: night lenses are used overnight and correct the shape of the eye’s cornea as you sleep. When the lenses are removed in the morning, you will have sharp vision without a visual aid. The effect is maintained for one to three days. The contact lenses must therefore be worn every night.
How do night lenses work?
Custom-made night lenses shape the outermost layer of the cornea overnight. This changes the refractive power of the cornea and facilitates sharp vision during the day. If the night lenses are optimally adapted to the eye and good hygiene is observed, application is completely harmless and is particularly suitable in the case of contact lens incompatibilities during the day. If you no longer use the contact lenses, the cornea returns to its original form in about three days. This method is therefore fully reversible.
Night lenses are applied before going to sleep and exert light pressure on the cornea.
Night lenses lie right on the cornea and the pressure means that the cornea reforms over time (approx. one week). Once the effect has been achieved, you no longer need to wear glasses or contact lenses during the day.
What are the advantages of night lenses?
- The ability to see without glasses or lenses during the day: the effect lasts between one and three days
- A simple way to correct visual impairment without a visual aid or surgical intervention
- In contrast to lasering, the original state can be restored
- Suitable for dusty or air-conditioned environments (carpenters, bricklayers or PC)
- Perfect for active people (athletes)
- Safe and quick familiarisation
- Correction of short-sightedness up to –5.00 dioptres and astigmatisms up to 2.0 dioptres
- In children, short-sightedness can be curbed
What are the disadvantages of night lenses?
Because the night lens ‘goes to work’ during the night, it is less suitable for people with irregular working hours, and at least 6 hours of sleep are required (shifts, night service). Anyone wanting to wear night lenses should have healthy eyes. It is therefore important that your ophthalmologist or contact lens expert advises you competently and regularly.
How can you get night lenses?
Would you also like to wake up in the morning and be able to go about your day without a visual aid? Then make an appointment with our contact lens specialists. After an in-depth contact lens and eye check, it will be possible to establish if night lenses are right for you.
New DreamLite® night lenses
Impactful study proves the efficacy of night lenses
DreamLite® night lenses have received European approval for slowing the development of myopia in children and young adults. DreamLite® night lenses can be used to control myopia in children with a correction of –0.75 dpt to –5.00 dpt and a cylinder to max. –2.50 dpt.
A two-year study demonstrates that DreamLite® night lenses reduce axial length growth in myopes compared to the control group with glasses by 63 per cent – this corresponds to an overall reduction of 0.32 mm.
Slowing progressive short-sightedness
Around the world, the number of short-sighted children and young people is growing considerably. According to projections, in 2050, almost 50% of the global population will be short-sighted. The more short-sighted (myopic) an eye is, the higher the risk of other conditions. Severe myopia can cause serious damage to the eye, such as retinal detachment, macular degeneration and glaucoma (excessive pressure in the eye). It is especially important to detect the risk of progressive myopia in children early. Visual impairments in the parents and siblings, ethnic origins, and the child’s lifestyle (using electronic media / time spent in natural light) are crucial factors in the development of myopia. Children are very capable of wearing and caring for contact lenses. The aim is therefore to slow the progression of myopia – which means managing it.
There now exist various possibilities to reduce the progression of myopia. Currently, one of the most successful options is orthokeratology, so supplying DreamLite® contact lenses, for example. Compared to a normal eye, a short-sighted eye is too long. The special design of an orthokeratology contact lens results in a different image on the eye’s retina. This takes away the eye’s impulse to continue growing in length.
Experience and expertise with night lenses
Our contact lens specialists at the Augenzentrum Kiener have many years of experience with night lenses. Night lenses have helped to manage the progression of myopia (increasing short-sightedness) in a targeted way and therefore slow it for many of our young patients. The official licence for DreamLite® contact lenses from our supplier Conil reflects our experience and encourages us to continue on this path.
