New technology lenses
Improving the quality of life of people with AMD
AMD , age-related degeneration , is a visual disease which affects more than one million French people, it is one of the leading causes of visual impairment in people over 60. This is irreversible, it is due to age but also to tobacco and blue light released by the screens of computers, tablets, smartphones, etc.
New solutions are available to us. Indeed, researchers from the University of San Diego and the Ecole polytechnique de Lausanne have developed a lens which, combined with a pair of 3D glasses , allows the patient to have a telescopic view. Through it he could see details up to 3 times bigger .
Zoom lenses
These lenses actually have two fields of vision . One magnified and the other is normal, when the wearer blinks his right eye, the lenses will begin to zoom, when he blinks his left eye, vision returns to normal. It is the coupling of two lenses that allows it to work in this way.
This innovative technology would allow many people to regain a quality life thanks to a single device. Today these lenses are rigid and not very comfortable, but researchers are working on a flexible lens, which allows air to pass through and is therefore more comfortable to wear.
An operation to fight AMD
Another solution exists for people with AMD: a surgical operation to graft a mini telescope into their eyes. Inserted in place of the lens, it helps to gain vision thanks to its magnifying properties. Additional hope for subjects with low vision and their loved ones.

Corneal modeling
Orthokeratology: Night lenses only
Corneal remodeling or Orthokeratology is an alternative to surgery for people with mild and moderate myopia and/or astigmatism . This practice is still uncommon in France but very widespread in Asian countries and even in the United States. Indeed, this one has already proven itself, it consists in reshaping the cornea via semi-rigid contact lenses which are worn only at night and which allow the patient to regain clear vision without equipment upon waking and throughout the day. .
However, it is essential to contact an ophthalmologist-contactologist trained in Orthokeratology to find out if your case is suitable for treatment.
How does corneal remodeling work?
Corneal remodeling consists of wearing semi-rigid lenses that have a particular shape during the night. By pressing on the cornea , they make it possible to correct vision without modifying the deeper cell layers. To benefit from this treatment, it is necessary that the sight is stabilized but there is no minimum age. However, it is mandatory to have good hygiene to avoid the risk of infection and irritation.
The risks of Orthokeratology
Like any treatment, there are several more or less dangerous risks:
- The lens can move during the night which would disturb the view the next day
– Eye infections and irritations if hygiene is not impeccable
– Have poor eyesight at night if the patient has to get up urgently (to take care of a baby, for example).
In order to avoid any problem, it is important to be followed by an ophthalmologist trained in Orthokeratology .
