Side-vision awareness glasses are an effective low vision device that increases the viewing field for people suffering from side vision loss.\u00a0<\/b><\/h2>\n

Side vision awareness glasses (SVAG) are an advanced optical technology used to widen the field of vision for patients with hemianopsia (hemianopia), or eye conditions such as retinitis pigmentosa<\/a>, that cause side vision loss.<\/p>\n

These SVAG increase safety for daily activities, and in some cases,\u00a0 even enable the ability to drive with side vision loss.\u00a0<\/b><\/p>\n

What is hemianopsia?<\/b><\/h2>\n

Hemianopsia is characterized by the loss of vision in half of the visual field, and is one of the most common side effects of a traumatic brain injury<\/a> (TBI), stroke<\/a>, and brain tumor.<\/p>\n

Imagine drawing a line down the middle of your visual field, and then only being able to see the image on one side of that line.\u00a0<\/b><\/p>\n

Hemianopsia can occur as a result of damage to the optic nerves, optic chiasm or visual processing regions of the brain. When any part of this system becomes damaged, partial or complete vision loss of up to half the visual field can result.<\/p>\n
