February is Low Vision Awareness Month

Low vision is a loss of eyesight that makes everyday tasks difficult. A person with low vision may find it difficult or impossible to accomplish activities such as reading, writing, shopping, watching television, driving a car or recognizing faces

Central vision
This is the detailed vision we use when we look directly at something. Macular degeneration (AMD) affects central vision. Diabetic retinopathy can affect central or peripheral vision.

Peripheral vision
This is the less detailed vision we use to see everything around the edges. Glaucoma affects peripheral vision first. Strokes can affect one side of the peripheral vision.

Contrast sensitivity
This is the ability to distinguish between objects of similar tones like milk in a white cup or to distinguish facial features. All eye problems can decrease contrast sensitivity.

Depth perception
This is the ability to judge the position of objects. New vision loss in one eye can affect depth perception, such as the height of a step.

Visual processing
The lens in our eye focuses light rays onto our retina. The retina converts these light rays into signals that are sent through the optic nerve to our brain, where they are interpreted as the images we see. A problem with any of these processes affects our vision in various ways. [Insert video: How the eye works and AMD video]

The experience of vision loss

It is always a shock to learn that your vision loss cannot be reversed. It is important to recognize the anger and frustration you may feel, to get help working through these feelings, and to apply the strategies of vision rehabilitation to stay active, including using low vision aids and low vision rehabilitation.
