A new research on May 27, 2011, suggested that wearing tinted lenses can reduce the Migraine Pain that is practiced by the Migraine patients. These lenses normalize the activity of the Brain.
The researcher Jie Huang, PhD, an Associate Professor of Radiology at the Michigan State University says that the patients of Migraine sufferers mostly get the pain due to the Visual Stimuli.
The further tells that these Visual Stimuli creates the discomfort and illusions that are disturbing.
The earlier studies of Jie found that vulnerability to these stimuli is due to the excess functioning of Visual Cortex in the Brain.
This excessive Brain activity can cause Migraine and the Tinted glasses can normalize the Brain’s activity.
Test on Migraine Patients
Huang and his friends know that there are certain patterns that can enhance the Migraine in people.
The researchers selected 2 groups 1 of 11 patients of Migraine and another group of 11 persons without Migraine problem. They made lenses for them known as Precision Ophthalmic Tints for every person.
They also made 2 other colored pair of Lenses such as Gray and other colors as comparison.
Then these participants were placed in the Functional MRI machine and they were exposed to the patterns that can enhance the distortion and discomfort.
The patients reported relief with all the lenses but the precision lenses worked better.
Huang says the use of controlled Lenses reduced the degree of Visual discomfort by 40% compared to without Lenses and the Precision Ophthalmic Tints reduced the discomfort up to 70%.
The Precision Lenses covered up the activation of Brain in the Migraine Patients.
The Migraine and the non-Migraine patients responded in the same way to the non-stressful patterns.
Haung says this shows that wearing the Precision Ophthalmic Tints Sunglasses can more reduce the Visual Stress as compare to wearing ordinary Sunglasses.
Huang says the Visual Stress can also be caused by the activities like reading, watching TV or working on computer etc.
He says the Precision Lenses can be fixed in to the regular Glasses.
The Cerium Visual Technologies, Ltd, in UK provided the Lenses for the research.
Arnold Wilkins the Huang’s co-researcher designed the device that is sued in the study to find the best shade of light for Visual comfort.
Kathleen Digre, MD, Professor of Neurology and Ophthalmology at Moran Eye Center at the University of Utah says, the use of Tinted Lenses is a new idea for the reduction of Migraine and Visual discomfort.
The researcher Kathleen was not involved in the research, she reviewed the study later.
Kathleen and her colleagues offer a Filter Lens known as FL-41. It is also useful in patients with the Migraine Problem or other light conditions.
She says the Tinted Lens was first used in England and it can reduce the Headaches by half.
She further says the important result is carried by the use of MRI. Something in the Brain is changed by the use of Lenses.
This research has proved a lot for the patients of Migraine but the work is still in process for further experiments.
