Photosyntonic Light Therapy

Neuro-Optometric Rehabilitation

Studies show that between 9-20% of school children have functional visual fields of less than 15*. This means that they have reduced peripheral range, better explained as tunnel vision.

Without peripheral vision, their awareness of their surroundings, both visual and auditory, are reduced. Additionally, approximately 7% of the population has either strabismus (eye turn) or amblyopia (lazy eye), affecting eye alignment, binocular vision and visual perception. These may manifest in decreased attention, productivity, comprehension, overall academic and lifelong performance.

Developed in the 1920’s, Photosyntonic Light Therapy makes use of our bodies’ natural response to light wavelengths to balance regulatory centers in the central nervous system, particularly the sympathetic and parasympathetic systems. Eyes are not just external organs to the brain, but are photocells of the brain.

60% of all nerve fibers in the brain originate in the eyes, and 80% of all perception is received through the eyes. Additionally, because 50% of our body’s blood volume passes through the eyes every 40 minutes, they provide a direct route to sensory input. When used in conjunction with Neuro-Optometric Rehabilitation, or Vision Therapy, Photosyntonic Light Therapy is proven to improve therapy efficacy and efficiency.light bar2

A functional visual field problem is a difficulty in how the person processes the information in their visual field. The problem causes the person to ignore a great deal of information in their periphery. This does not mean to imply peripheral blindness but an ignoring of peripheral information by the brain.

These types of field conditions are related to “inadequate functional visual abilities and overall learning and performance deficits”.

The patients most likely to benefit (from light therapy – a treatment our clinic incorporates into every vision therapy program) have not just one or two but several visual deficits including but not limited to accommodative dysfunction, binocular disorder, and poor visual processing skills.
