Who is sight Connection?

We are a Seattle-based non-profit organization. All proceeds from sales on this website go directly to funding our programs supporting people with low vision and blindness.


Our mission is to enhance the ability of people with vision loss to lead active, independent lives. Our motto:


Who We Serve

What does it mean to be low-vision, or visually impaired?
Low vision is a partial loss of sight (also referred to as partially sighted, severe vision impairment). It is often a loss of visual acuity or sharpness, but may be a loss of side vision or extreme difficulty with light or glare. Low vision exists when functional vision cannot be adequately corrected with eyeglasses, contact lenses, medications or surgery.

Legal blindness is a level of visual impairment that has been defined by law to determine eligibility for benefits. It refers to a central visual acuity of 20/200 or less in the better eye with the best possible correction, as measured on a Snellen vision chart, or a visual field of 20 degrees or less.

The Four Most Common Causes of Vision Loss

Age-Related Macular Degeneration (AMD):

Age-Related Macular Degeneration (AMD) is the leading cause of irreversible severe central vision loss in Caucasians over the age of 50 in the U.S. The incidence and progression of all the features of AMD is known to increase significantly with age. It results from damage to the macula, which is the central part of the retina responsible for central vision and ability to see detail. Although the extent of central vision loss can be significant, macular degeneration alone rarely causes total blindness.


Glaucoma in its most common form is the second leading cause of blindness in the United States, and the leading cause of blindness among African-Americans. Glaucoma is a disease where pressure within the eye is so high that it can damage the optic nerve and lead to vision loss. It affects side vision long before central vision is affected. Although glaucoma cannot yet be prevented, it can usually be controlled or stopped with treatment and medication.

Diabetic Retinopathy:

Diabetic Retinopathy is a complication of diabetes caused by damage to blood vessels in the retina. It is one of the four leading causes of severe vision impairment in older Americans. The risk of developing diabetic retinopathy is greater the longer someone has diabetes. According to the American Academy of Ophthalmology, about 80 percent of people who have had diabetes for at least 15 years have some damage to the retina.


Cataract is a clouding of the lens of the eye, which is normally clear. Light can no longer pass through the lens easily, and vision becomes hazy or blurred. The current treatment, which is safe and highly successful, is surgical removal of the lens which is usually replaced with an intraocular man-made lens.
There are many other conditions that can cause a significant loss of vision. It always best to consult with your eye care physician about any concerns with your vision and to get regular eye exams.
