Does your lack of side vision leave you missing out? Afraid of accidents or walking into people? Concerned about your safety? There is help…

Side Vision Awareness Glasses Can Help

Side Vision Awareness Glasses™ (SVAG) was developed by Dr. Errol Rummel of Jackson, NJ, after years of treating people with stroke-related, or brain injury related hemianopsia (side vision loss). Dr. Rummel is Director of the Low Vision Care Center, Jackson, NJ, and is the Director of the Neuro-optometric Rehabilitation Clinic at the Bacharach Institute for Rehabilitation, Pomona, NJ.

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.

Vision Loss From A Stroke

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).

Regain Your Independence

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’s suffering from side vision loss, or care for someone who has side vision loss, please call Dr. Rummel at 888-838-0188 for a free telephone consultation. He can answer your questions and determine if you're a candidate for improved side vision with Side Vision Awareness Glasses.

What Makes Side Vision Glasses More Effective For People With Side Vision Loss?

Dr. Rummel utilized his extensive experience and expertise to develop Side Vision Awareness Glasses that solved issues in other glasses that tried to assist stroke patients to increase their field of view. SVAG have important advantages over previous attempts to develop field expansion:

Barely Noticeable Smooth Lens


SVAG are more attractive because the front of the lens is smooth. When the glasses are worn to improve side vision awareness for stroke-related vision loss, the lens is barely noticeable, a big concern for many patients that do not want to advertise to the world their vision condition.

Reduce Color Aberrations


SVAG have a high ABBE value, so they reduce distracting color aberrations seen through other lenses. This increases your visual focus and improves functional vision.

Quality Construction


SVAG are less likely to accidentally break because there is no glued seam splitting through the lens from front to back as found in older attempts at field expansion.

Better Contrast Sensitivity


Thanks to better contrast sensitivity than found with Fresnel-lens based glasses, SVAG provide improved vision.

Look Great and See Great


Side Vision Awareness Glasses have a higher index of refraction, so SVAG is a thinner and more cosmetically acceptable lens, without an obvious line on the front of the lens, and without an unsightly thick button, or lens strip inserted through the front of the lens.

Easier To Use


Side Vision Awareness glasses for hemianopsia are easy for people to use because they don’t superimpose a narrow peripheral image over a person’s central vision (which is confusing and difficult to learn to use).

The Widest Viewing Angle


Side Vision Awareness Glasses have the widest viewing area, allowing better field awareness in the direction of the hemianopsia than button lens systems. And because SVAG has 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.

What Our Patients Are Saying About Side Vision Awareness Glasses

Walking in rural or urban areas I am more aware of my surroundings and can better avoid bumping or tripping

“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.”

They help me maneuver through obstacle courses of items such as carts or floor displays.

“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.”
