One of the effects that brain output produces is a regulatory control over the motor cells of the spinal cord. In many cases, this control mechanism often becomes compromised by the imbalance of output between the two hemispheres. The Low Frequency Reversible Frame Hemifield glasses are designed with dual-colored lenses vertically dividing the visual field into red and black. The color black produces a greater sedative filtration than red and if the glasses are worn with the black lens panel to the right, the frequency of visual sedation to the left- brain is greater than to the right.

To understand how this works, we will need to review the receptors and fiber tracts as they leave the eyeball to terminate in the brain. The inner wall of the eye is covered by light sensitive receptors located in a layer of tissue known as the retina. The nerve fibers that leave the retinal receptors along the eye's nasal wall cross over to enter the brain on the opposite side. Those receptor fibers that leave the retina from the outer-side wall (also referred to as the temporal wall) do not cross over but remain on the same side to terminate in the hemisphere ipsilaterally to the side of the eyeball.

Therefore, if the glasses are worn with the black filter coating on the right and the red filter on the left, the light entering the eyes though the black filters, will result in a significantly lesser activation of the retinas’ receptor fields than the light transmitted through the lens’s red filter segment.

Let’s look at this buffered stimulatory process as it relates to the right and left eyes.

First the right eye: As light passes through the outer black filter half of the glasses’ right lens to enter the right eye, the black filter’s enhanced sedative influence terminates along the retinal lining of the eye's inner nasal wall. Normally, these receptors transmit through nerve fibers that cross to the left-brain but because of the sedative modulation from the black filter their signals are significantly tranquilized and the outcome is a lesser activation of the left hemisphere’s primary visual cortical neuronal pools. The light that enters the right eye from the left visual field passes through the red (low frequency) filtered portion of the right lens and terminates on the right eye's outer temporal retinal wall. Although the retinal receptors that dwell in this region of the eyeball are also undergoing a buffered sedative input, the red filter has a lesser sedative influence than its adjacent black filter and therefore allows for a higher frequency of signal transmissions. However, these retinal fibers do not cross and as a result terminate in the primary visual cortex of the right brain. 

Now let’s look at the left eye: Again, light which passes through the black filter portion of the left lens enters the lens from its nasal surface and terminates on the temporal inner surface of the left eyeball. These retinal fibers stay on the same side as they enter the brain and profoundly sedate the left cortex. The light that passes through the outer red lens portion terminates on the inner nasal retinal surface and transmits a low frequency signal, which crosses over to the right brain. Hence, the light stimulus has been divided into a greater sedative calming to the left-brain and a mild filtered stimulus to the right, which inadvertently results in a significant sedation of the left cerebral cortex over the right. If we consider the laws governing neuronal principles, it is well known that each time a nerve or pool of nerves becomes facilitated or inhibited the nerve cells undergo a sequence of events known as early gene expression. This is a process in which the nerve cell synthesizes proteins and develops its inner structures and organelles to become stronger and more viable (Making the cell do push-ups). Consequently, in the case of a right cortical deficiency in a subject with a low metabolic capacity the result of sedating the left hemisphere greater than the right should increase the nervous system's central integrated state to a level of greater regulatory balance and quality of life. 

Like all devices that can aid the body, if it can help, it can also offend. Always monitor autonomic indicators such as heart rate or blood pressure while administering treatment protocols. 

  • The Hemifield Sedator Glasses are secured within a reversible frame for easy alternation between right and left hemisphere sedation.
  • Made of the highest quality non-prescription lenses, each lens has been colored with a special molecular fusion dying process to ensures against fading or smearing.


**Reversible goggles have been attached to the existing metal frame to enhance peripheral visual restriction.**
