Side Vision Awareness Glasses ThumbnailHemianopsia, the loss of up to half the width of your field of vision, is one of the most common side effects of a stroke, tumor, or traumatic brain injury. It can leave you disoriented and struggling to make it through the day. People find themselves afraid to go out due to concerns about their safety. 

Imagine taking a pen and drawing a line across the middle of your vision. Imagine you cannot see anything on one side of that line – this is what many people with hemianopsia experience.

Side Vision Awareness Glasses (SVAG) is an advanced optical technology developed by Dr. Errol Rummel that specially trained low-vision doctors throughout the United States and Canada now prescribe. For a list of trained SVAG doctors, go to: www.SideVisionAwarenessGlasses.com

SVAG enables people with side vision loss to perform daily activities more safely, and some patients who use SVAG may even be able to drive. The width of side vision improvement varies and is determined during specialized testing.

SVAG can also help many people with constricted side vision loss due to eye diseases of the peripheral retina, like retinitis pigmentosa.

We know how side vision loss can negatively impact your life, and as trained SVAG low-vision optometrists, our goal is to keep you independent with the help of Side Vision Awareness Glasses.

What are the Causes and Symptoms of Hemianopsia?

Hemianopsia can occur when there is damage to the optic nerves, optic chiasm, or visual processing regions of the brain. 

When any part of this system is damaged, the result can be a partial or complete vision loss in up to half the visual field.

Symptoms may include:

  • Bumping into objects, such as door frames, furniture, and people
  • Difficulty driving, especially when changing lanes or attempting to avoid objects on the side of the road
  • Frequently losing your place while reading or having trouble finding the start or end of a line of text
  • Difficulty finding or reaching for objects on desks or countertops or in cabinets and closets

If you suspect you may have hemianopsia, speak with your low-vision optometrist today. 

What are Side Vision Awareness Glasses?

Side Vision Awareness Glasses (SVAG) assist people with side vision loss. It is an effective low-vision device that increases a patient’s viewing field. Having a wider field of vision improves the patient’s safety and boosts their confidence and independence. 

SVAG are made from customized lenses that have many advantages over standard prism optical lenses:  

Flatter Lenses

SVAG is aesthetically pleasing because the area with the SVAG optics is barely noticeable.

Fewer Color Aberrations

SVAG has a high ABBE value, which helps reduce distracting color aberrations seen through other lenses, increases visual acuity, and improves vision.

Better Contrast Sensitivity

SVAG provides improved vision because they offer better contrast sensitivity than the Fresnel lens-based prism glasses.

Easier to Use

SVAG is easier to use than the old technology button lens systems and offers better side vision awareness than the old Fresnel prism glasses because the Fresnel prism glasses provide a narrow peripheral image over your central vision — meaning you see two images simultaneously. In contrast, SVAG provides only one image to view, which is much less confusing and easier to adapt to and learn to use.

Get your life back with Side Vision Awareness Glasses. Contact one of the IALVS low-vision optometrists for an SVAG evaluation so that you can experience a higher quality of life and function better with improved side vision awareness.
