PHOSPHENES : the stimulating effects of Light on brain functions

Note :
The world is changing, and, with it, new technologies are developed. The medicine of the past is not today’s medicine nor it is the medecine of the future. Thanks to the works of Dr Francis LEFEBURE, the "ancient" and "archaic" Initiations of the past are superseded by techniques based on the most elementary laws of cerebral physiology and which are exempt of concepts based on dogmas.

In 1959, while he was a doctor at the School Health Service, Dr. Francis Lefebure discovered and analyzed the stimulating effect of light on brain functions. His method is based on "phosphenes", the multicolored spots that persist in the dark for 3 minutes after having focused on a strong light source for 30 seconds.

The extraordinary discovery of Dr. Lefebure is that MIXING A THOUGHT WITH A PHOSPHENE TRANSFORMS THE ENERGY OF LIGHT INTO MENTAL ENERGY. Phosphenes stimulate the development of memory, intelligence, attention, creativity, intuition, ...

Many people like to read in the sun, as it casts a very strong light on the book.

Usually, when you read in a room, the light is indirect or too far from the text, or perhaps even too weak for allowing the production of a phosphene, whereas the reflection of solar light on a book produces a phosphene by its reflection on the white page.

At a very young age, Dr Lefebure made the following observation:

Up until the age of 12, I was a dunce at school and I suffered from it very much. It was to such a point that when I was 11 years old, my teacher wanted to definitively expel me from high school and I was able to stay only thanks to the energetic intervention of my grandmother. But, when I was twelve, after the Easter holidays, I suddenly became a good student in a way that was so unexpected that my classmates carried me in triumph around the schoolyard. Later on, I was always among the best students in sciences.

So, what happened during these famous Easter holidays? We had moved. Before, I was living in an apartment where there never was any sun. The new apartment was magnificently bright and I acquired the habit of studying often with the sun‘s light shining on the book, although some people claimed that I would hurt my eyes. But, that was not so. And quite to the contrary, it was from that moment on that I became a good pupil. I believe that this event is a kind of foreshadowing of my researches on phosphenes. »

We understand a text better and remember it better if it is strongly lit. If this is done with a light bulb, we must be careful that it is set in a deep metal reflector, to avoid the rays shining directly in the eyes. If it is the sun that lights our text, we need to turn our back three-quarters to it so that only the book receives the light.

Afterwards, I was always among the best in sciences, and I was among the first in the P.C.N. (Physics, Chemistry, Natural Sciences), in the preparatory year in Medicine, even though there were more than four hundred candidates in this session and I was among the youngest (17 years old).”


A phosphene is produced by focusing, for approximately 20 seconds, on a opaque white "natural daylight" light bulb placed at a distance of two to three yards (2-3 meters). These short periods of focusing are not tiring for the eyes and, on the contrary, constitute an excellent eye exercise. In the dark, the phosphene appears in the form of a patch of changing colors which persists for three minutes.

Note from NEEEEEXT :
a simple opaque LED, incandescent or halogen bulb (75W to 100W equivalent) of white light (daylight) in which you cannot see the filament and that does not have a brand printed on the top is recommended (but don't use a neon light for mixing!).
Distance : 2 to 3 meters.
Duration : 20 to 30 seconds.

A desk lamp (as shown below) with a white reflector can also improve the quality of the phosphenes.


The colors of the phosphene.


After switching the lamp off, you will perceive:

– A very short green phase
– Then, for the first minute: a yellow phosphene surrounded by a red border
– Then, during the next minute, the dominant color of the phosphene is red/pink
– Then, during the third minute, the phosphene is blue

Note: depending on the person, the phosphene used for educational purposes can last between 3 and 4 minutes and it can be subject to brief periods where it disappears.


Doing phosphenes by themselves develops nothing or nearly nothing in the mental domain, only Phosphenic Mixing develops all the intellectual faculties as a whole. "Mixing" means "blending".

Phosphenic Mixing consists of mixing a thought and a phosphene.

This combination is made over a certain amount of time (by holding a precise thought chosen in advance during the presence of the phosphene), or at the same time in time and space (by placing the visual or auditive mental image inside the phosphene). That second way of proceeding is more effective, but more difficult.

In order to obtain concrete results in the development of mental capacities, it is necessary to associate phosphenes with your work, studies or subjects of reflection.
For learning a mathematics lesson, the student thinks about the formula he is studying during the phosphene‘s presence.


There is no limit to the number of phosphenes that can be done during a session. Many students practice several hours in a row without the slightest amount of fatigue, focusing every five, ten or fifteen minutes depending on the subject being studied. Children only need to do their homework and learn their lessons using phosphenes to see the grades in school improve quickly.

Students and adults often study several hours in a row because of the great number of subjects in the programs of study. All they have to do is associate phosphenes with their studies, that saves time and allows the accumulation of a considerable amount of energy in thoughts and the nervous system. Therefore, one should systematically do as many phosphenes as possible while studying.

Phospheno-teaching is not only a method that allows one to work more efficiently: it is above all a technique which allows a real blossoming of the personality.

That is why Dr Lefebure made the distinction between two separate areas of application: the study of rythmo-phosphenic techniques on one hand and the educational method on the other hand, which he developed in his book ‟Phosphenic Mixing Applied to Education”, a method for which he was awarded the Silver medal at the Inventors Fair in Brussels, in 1975.

Long misunderstood, the practice of focusing on light sources was considered to be a simple rite whose meaning and importance ended up being forgotten by certain traditions and practices. Nonetheless, it is not a question of utopia or even faith, which is only a last resort for reassuring oneself. The initiatory experience begins now; in other words, it is a part of everyday life. It enriches life because it provides a ‟new” means for understanding it. It is no longer an empty hope but a considerable number of benefits in everyday life. And we can test it for ourselves if we really want to. Dr Lefebure has given us the means. Phosphenic Mixing Applied to Education is certainly the most beautiful gift that he offered to humanity! It is up to humanity to put it to use…

The Ancients often said: ‟Light is the source of knowledge”.
Today, thanks to the works of Dr Lefebure, we understand why.


Teachers who use the phosphenic method in remedial courses at school tell us that the parents are the first to be surprised by the results obtained, and the progress made is so obvious that they ?are astounded” by it.

Apart from the increase in cerebral energy provided by phosphenes, reading with phosphenes is the only method which allows to:

– increasing the speed of reading and, consequently of studying,
– increasing the capacity of memorization,
– and, very importantly, facilitates the understanding of the content of the subjects studied.

Developing memory and intelligence by combining thoughts with phosphenes.


Phosphenic Mixing makes problems of dyslexia and dysorthographia disappear, as these two problems are caused by the practice of making children conform to rules and habits which do not correspond to their cerebral rhythms.
Thanks to phosphenes, many children and adults have successfully been able to overcome these problems which are very wide-spread and often continue into adulthood if they are not treated.


The application of the method is easy and even enjoyable: children will spend the same amount of time studying as they normally would, but they will be able to memorize information better and will benefit from a development of cerebral capacities that will remain between the sessions.

Each different school subject has its mode of application: English, History, Geography, etc. In the case of mathematics, thinking will be more structured, and the information related to the question will be better assimilated. Significant progress and results will be observed quickly. Mental arithmetic exercises will become easier. The capacity to appreciate unfamiliar points of view will expand; the ability to formulate ideas for essays will be enhanced. For the study of a foreign language, phosphenes will help memorizing new words, grammatical structures, and will help acquiring the right accent and intonation.


Children learn faster, remember their lessons easier and are more attentive in class. The effects can be felt from the first session.


In Portugal, Professor Cruz from Lisbon, was commissioned by the government to perfect the educational methods of his country, and performed attention span tests with children, before and after a session of Phosphenic Mixing. It has been confirmed that cerebral capacities are enhanced after each session and that by repeating practice over a few weeks, half an hour a day, the improvement of the children’s attention span persisted between sessions.
Specific problems like DYSLEXIA, STUTTERING, SPELLING DISORDERS as well as FAILURE AT SCHOOL can be corrected within a few months.


When phosphenes are associated with any traditional or modern exercise of personal development, the effects are multiplied in a considerable way. That way, phosphenes can be used to obtain the development of memory, attention, intelligence, the spirit of initiative and creativity. The method is thus a wonderful educational tool.

For nearly 40 years, Dr. Lefebure’s book ?Phosphenic Mixing Applied to Education” has helped thousands of children and students to pass their exams, and thus efficiently helps solving failure at school. Given all the problems in the school system today, more and more parents are using Phosphenism, as well as teachers who use the method in their remedial classes with considerable success. ?Phosphenic Mixing Applied to Education” is now in its 17th edition.


Reading with phosphenes is done with the eyes open; the phosphene can be perceived just as well with the eyes closed as with the eyes open.

You need to equip yourself with two lamps, one with a special "daylight bulb for doing phosphenes, and the other one, a simple desk lamp, for lighting the text because at the beginning the phosphene will be very intense and can hamper reading.

When a student is reading during the presence of the phosphene, the main ideas are better grasped, including the main and secondary ideas. The meaning of the text as a whole is understood better. The overall structure of the text is assimilated better and the student is able to identify its various components much easier. In the course of time, and on the condition that they read their lessons every day using phosphenes, students will notice that they learn faster and retain information better. Significant results are shown in marks at school and teachers are surprised by the improvement in grades.


Students notice that they understand better and assimilate information faster. Their ideas become much more structured.

People who take up studying again after a long period of intellectual inactivity, will notice quickly that their ability to concentrate improves, that they work faster and memorize more information about more varied subjects.

Adults can also benefit from this method in many ways: memory is stimulated, self-confidence is increased and creativity is developed. Nervous and physical resistance is enhanced, making it easier to cope with stress. But Phosphenism is not only a method that helps one to work more efficiently: it is above all a technique that achieves a true, independent development of the personality.

The action of Phosphenic Mixing on sleep patterns is remarkable : many cases of insomnia have been cured by the method. Dreams become more colorful, logical and conscious.

The effects on eyesight are very positive. If the precautions we recommend are followed, the practice of Phosphenic Mixing is particularly beneficial, whether for the functions of the brain or for the health of the eyes themselves. These norms have been established by more than 30 years of experimentation with tens of thousands of cases.

Older people will experience a cerebral rejuvenation.
