LightVision fights AMD

LightVision, augmented reality glasses against AMD

The Start-Up LightVision has developed new augmented reality glasses . These will allow the visually impaired who wears them to see images projected onto their retina. In addition, they will be equipped with new technology: Eye-tracking which would make it possible to follow the movements of the pupil and to correct visual diseases.

LightVision to help people with AMD

AMD is a visual disease that causes loss of central field of vision . This is irreversible and cannot be cured. This is why today many companies, including LightVision, are looking for glasses and technologies that could improve the quality of life of these people.
Indeed the company explains that "The goal of LightVision is to visually help people with AMD, a disease that affects about 1.5 million people in France and more than 60 million worldwide . This disease of the center of the retina gradually leads to the loss of central vision, forcing the patient to use his peripheral sight, unfortunately very inaccurate and not very sensitive to contrasts and colors”.
Augmented reality glasses will be implemented thanks to two cameras placed in the branches who film the patient's environment. People with this visual disease will therefore be able to view their environment correctly and more easily thanks to close-ups and amplified luminance.
The engineers and inventors of this start-up should market these glasses shortly at a price of 7000€.

A great hope to help these patients get out of the blur.

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.

Les aliments bons pour votre vue !

Foods that are good for your eyesight!

Good food for good eyesight!

makeup eyes

We think of paying attention to what we eat to improve nail growth or to have shiny and healthy hair, but our eyes are often neglected!

Yet they also require that we take care of (y)them , starting with what we put on our plates.

A good diet makes it possible to avoid all sorts of inconveniences due to certain deficiencies , such as AMD (age-related degeneration), glaucoma or quite simply to avoid worsening an already existing sight problem .

To begin with, a balanced and varied diet helps maintain a healthy overall lifestyle.

Here is our pick of the best foods for healthy eyes:


These are polyunsaturated fatty acids that are necessary for the proper functioning of the human body but that it cannot produce by itself. They must therefore be found in the foods we eat. They are present in large quantities in nuts, chia seeds, flax seeds, in shrimp and in fatty fish such as herring, salmon, sardines, etc.

omega 3 salmon

Vitamins A, B, C and E:

- Vitamin A is one of the molecules that make up the retina , it helps protect the cornea. It becomes very useful during conjunctivitis, glaucoma, cataracts or major vision problems , indeed a vitamin A deficiency would cause total blindness .

Vitamin A is found in calf's liver, carrots, broccoli, spinach...

- Vitamin B improves eyesight and prevents its decline , especially the "sub-vitamin" B2, riboflavin.

It is found in abundance in foods of animal origin such as cheese, eggs, meat or fish. It is also found in green vegetables such as spinach, asparagus or even in cereals or brewer's yeast.

- Vitamin C plays an important role in reducing the risk of cataracts and AMD . Indeed, the retina and the lens are bathed in a fluid with a very high vitamin C content . It is therefore necessary to ingest vitamin C to allow a good balance.

Vitamin C is easy to find in large quantities: in citrus fruits, red fruits such as blueberries or blackberries, broccoli, peppers...

- Vitamin E would have a protective effect against AMD and cataracts . It would reduce the progression of these disorders .

A daily dose of it by eating for example almonds, hazelnuts, sunflower seeds, avocados, etc. would provide protection against these diseases.


It is a very good element in the preservation of your sight and the good health of your eyes , it is found in cocoa, wheat germ, eggs, cashew nuts.

In order to have healthy eyes, integrating these foods into a balanced diet is the solution. When the good weather arrives, it is easy to find many fresh products rich in vitamins and minerals. It is also possible to take food supplements to complete a varied and balanced diet. But like everything, be careful with the doses taken, an overdose would cause negative side effects.

Foods to avoid:

A diet too rich in omega-6 including too many vegetable oils, seeds, eggs or certain meats would tend to cancel the effects of omega-3.

Processed foods of industrial origin which have little nutritional value and therefore no vitamins, minerals, necessary for the functioning of the body in general.

An unhealthy body will lead to vision problems as you age.

The aging of the eye

The aging of the eye, a subject that concerns us all!

Our tissues and organs age . Unfortunately, the eye does not escape this harsh reality. Today it is important to protect his eyes against the ultraviolet rays , blue light and for some infrared . The aging of the eye is a subject that concerns all individuals, it is necessary to have ophthalmological and optometric check-ups once a year.

The aging of the lens

The lens is simply the lens that sits inside the eye, just behind the iris (see diagram). This one deforms by pressure from the ciliary muscle. This deformation allows to have a clear vision, it is the accommodation. The lens becomes less and less flexible over the years and this leads to the symptom of “arms that are too short”, presbyopia.
After Presbyopia, it is the transparency of the lens which is reached, the crystalline lens becomes opacified especially with exposure to the sun and blue light: this is the cataract .

The aging of the retina

The retina and its central part, the macula , allows to see the details, it is what allows the individual to be able to read and recognize shapes and faces. The aging of this can be very disabling, this is called age-related macular degeneration: AMD

The aging of the optic nerve

The optic nerve is simply the " messenger », the one who will transmit the visual information from the eye directly to brain . With age there is a decrease in the number of nerve fibers originating from the retinal ganglion cells. This reduction in the fibers of the optic nerve is accelerated in the event of chronic glaucoma, a disease whose incidence increases with age.

Aging tear glands

The eye is permanently soaked with tears secreted by the lacrimal glands . The secretion of his tears decreases with age, which can lead to eye dryness .

Aging tear ducts

The tears are processed by lacrimal ducts to the nasal cavities. With age, these pathways can shrink and/or clog . This results in individuals with intermittent or permanent tearing. If this discomfort is too great then it is possible to go through the surgery .

Vitreous aging

The vitreous is a transparent and homogeneous gel inside the eye. With age, certain parts liquefy, condense... Which leads to the appearance of " flying flies 'or' flashes of light ".

PIXIUM VISION: restoring sight, restoring life

Pixium Vision, the Iris project comes to fruition

A young French company, Pixium Vision has been bringing new perspectives to the visually impaired or blind for several years; indeed it will be able to help more than 4 million people through the Iris project. This consists of restoring part of the visual functions of the blind. in order to restore their sight. State-of-the-art technology that would allow blind patients to return to a "normal" life.

A great step forward for optics

With the project of making the view thanks to simple implants , the French company is revolutionizing the world of optics and brings real hope to these many patients with blindness. Pixium Vision has announced European approval for its artificial retina. Once this standard was validated by the European Union, the marketing of Iris quickly began. This new project has 3 times more electrodes than the first version, which would provide patients with vision as close to normal as possible. This week Pixium Vision successfully implanted and activated its Iris II bionic eye in a Spanish patient.

The new project of the French company Pixium Vision

The company does not stop there and is currently working on other projects in parallel such as Prima . This consists of the creation of a sub-retinal implant which would improve the sight of individuals suffering from age-related macular degeneration (AMD). Pixium Vision is also looking for solutions for patients with retinopathy pigmentosa.

Let's not forget that, whatever our age, it is important to protect ourselves from AMD, one of the causes of this visual disease: harmful artificial blue light given off by screens. So when you are in front of your computer, television, smartphone or even your tablet adopt the right gesture, wear a pair of sunglasses with a “Cool Blue” treatment.

OMEGA 3 and eyesight

The eye by its complexity is a marvel of nature . It captures light, analyzes it and interacts with its environment. It is necessary to preserve it and keep it healthy for as long as possible. Because sight is life , through this article we will explain to you how OMEGA 3 play an essential role in preserving our vision. Indeed, food hygiene and the right balance between OMEGA 3 and OMEGA 6 make it possible to protect and maintain vision over the long term.
