Side Vision Awareness Glasses™ (SVAG) were developed by Dr. Errol Rummel, an optometric physician, after years of treating people with stroke-related, or brain injury related hemianopsia (side vision loss). Dr. Sapossnek has been personally trained and mentored by Dr. Rummel.
Having designed and prescribed hundreds of optical systems to expand side vision, he realized a more effective optical field expansion device was needed, and that a detailed system was necessary for doctors to learn how to accurately examine, prescribe, and instruct a patient in using such a device. He learned what worked and what didn’t work, and designed an advanced optical technology called SVAG (Side Vision Awareness Glasses) and devised a protocol to be used by doctors in order to effectively examine and prescribe the special glasses for those with hemianopsia.
SVAG have important advantages over previous attempts to develop field expansion:
SVAG have optically clear lenses, without the distracting aberrations or blur of press-on prism systems.
They are a cosmetically acceptable lens system, without an obvious thick round prism button inserted through the front of the lens, and without obvious Fresnel prism strips inserted through the front surface of the lens.
Thanks to better contrast sensitivity than found with Fresnel-lens based glasses, SVAG provide improved vision.
SVAG have the widest viewing area, allowing better field awareness in the direction of the hemianopsia than button lens systems. And because SVAG have a vertical edge, the person with hemianopsia just needs to move their eyes a couple of millimeters to get into the SVAG area of the lens, instead of having to travel past the curve of a button lens in order to find the widest possible viewing area.
SVAG are easy for people to use because they don’t superimpose a confusing narrow band of peripheral vision above, or above and below, a person's central vision, which can be difficult to learn to use.
SVAG look more like regular glasses, because the SVAG lens line is barely noticeable.
SVAG have the advantage of having been used successfully for years by hundreds of happy patients, and can only be prescribed by eye doctors trained in the Rummel Side Vision Awareness Glasses System.
Hemianopsia can leave people disoriented, insecure, and struggling to make it through the day. In addition there are hemianopsia-related safety issues, such as bumping into furniture, walking into people at the mall, falling off a curb, and difficulty performing other activities of daily living. SVAG can give those with hemianopsia more freedom, independence, and safety. Using SVAG may even allow some of those with hemianopsia to return to driving (which may require special on-the-road testing and Motor Vehicle Department approval, depending on state law).
Hemianopsia (loss of half of the width of your field of vision) is one of the most common side effects of a stroke or traumatic brain injury. It can leave a person disoriented, and struggling just to make it through their day. People can find themselves afraid to go out, concerned about their safety.
If you’re suffering from side vision loss, or care for someone who has side vision loss, please call Dr. Robin Sapossnek at 215-663-5933 for a free telephone consultation. She can answer your questions and determine if you're a candidate for improved side vision with Side Vision Awareness Glasses.
“The Side Vision Awareness Glasses bring the objects toward the left into my vision. Most noteworthy has been spotting hanging traffic lights installed on the left hand side of the street, bringing them into full view. Walking in rural or urban areas I am more aware of my surroundings and can better avoid bumping or tripping. On the lighter side when sitting in the passenger seat of the car, I am able to see the speedometer and monitor my husband’s speed.”
“The use of Side Vision Awareness Glasses has been very helpful when shopping, helping me to avoid items left by clerks on the floor. They also help me maneuver through obstacle courses of items such as carts or floor displays. Also while walking in the neighborhood, I can more easily watch for cars before crossing the street.”
