Your eye, a precious gift

Sight is our most called-upon sense.

It allows us to perceive colours, shapes, positions. It is essential for us in order to integrate into and appreciate fully the world around us and to communicate with others. Contemplating nature, observing a painting, reading a book, travelling, working, creating and of course many other things !
The human eye is directly connected to the brain. It is a globe of 2.2 to 2.5 centimeters in diameter and weighs between 7 and 8 grams. It owes its mobility to 6 extra-ocular muscles dedicated to the fixation and the movement of the eyeball. A 7th muscle controls the upper eyelid.
Highly efficient, the eye is a complex and fragile organ. To preserve it, and thus keeping your eyesight healthy, regularly consult your ophthalmologist.


We can compare our vision to a camera or video recorder! The function of the ‘diaphragm’ is held by the pupil, located in the center of the eye (the black opening). It is the lens that focuses, just like the lens of a camera. Finally, the retina transforms the received light into electrical impulses that the brain translates into images.

Ultimately, it is the brain that delivers vision. The eye and its appendages are intermediate organs.

In the spotlight ! 

Unlike some animal species, humans cannot see without light. All the luminous rays that enter the eye are regulated by the iris. The diameter of the pupil is adjusted according to the amount of light. In full light, the diameter of the pupil is reduced; This is called miosis. If it is night or you’re in the dark, the pupil dilates (a phenomenon called mydriasis) to allow maximum light to enter the eye. The luminous rays pass through the layers of the eye such as the crystalline lens and the vitreous body. In order for the brain to correctly interpret the luminous flow, the vision of the two eyes must be coherent.
n some cases, each eye transmits a different image to the brain causing visual disturbances. We can note for example; strabismus (cross-eyes): each eye sends a different image to the brain because the two visual axes do not point to the same object. If the abnormality is not corrected early enough, the brain may, by force, obscure the image of an eye.
It is useful to know that for each individual, one of the eyes is dominant. Knowing which one is important for some sports, like shooting.
