Can Posturology improve vision?
If you have been told once that you need glasses or contact lenses for a refraction problem, you most likely did not question it. You were maybe even told that there isn’t much you can do about your far or near sightedness. Somehow we don’t think twice about what can be done to optimize vision.
How about if glasses can make your eyes lazy? Would you want that? Would you want to change that around?
Here is a crash course on vision:
There are two components to the eye that actually allow you to project light rays on the retina, which, in the end, allows you to see:
Although the cornea and the lens share the common goal of projecting light rays on the retina, both have their specialty.
The cornea is the first organ of the body to manage light rays to send them to the retina. As long as what you are looking at is 90 centimeters away from you or more, it is indeed your cornea that does just about all of the work in terms of projecting the light rays on the retina. The retina sends the information to various parts of your brain, via the optic nerve, and you see.
If the object of interest is within 90 centimeters, Posturology can truly help improve vision. The reason is simple.
To focus on the object of interest, within 90 centimeters, your eyes need to move together on the target of interest. In order to do so, muscles from both eyes need to be utilized in synergy. These muscles, like any others in the body, can be trained. They are the EOM (extra ocular muscles). There are 6 of them per eye. When your eyes move together, your focus is better and your eyes can more easily land the light rays on the fovea (where the visual acuity is the greatest on the retina). The net result is that you can see with more precision and we look for this precision every time we lay our eyes on a target.
The second reason as to why Posturology can help with vision is closely related to the first. In fact, this time it has to do with muscles located inside of the eyes. The ciliary muscles are responsible for mobilizing the lens. When an object is seen within 90 centimeters, the lens needs to be mobilized to maintain focus. The muscles that mobilize the lens can be strengthened as the EOM. In fact, both are strengthened simultaneously in the context of ocular exercises that are suggested to the patient in Posturology.
As you can see in this image, the ciliary muscles mobilize the lens. The lens adjusts the focus so that we can see sharply when our focus is to be made close up.
Posturology, because its primary concern is sensory input to the body, helps in many cases. Vision is simply one of the health conditions that can be improved, functionally.
