Low vision means that even with regular glasses, contact lenses, medicine or surgery, people find everyday tasks difficult to achieve. Most people develop low vision because of eye diseases and health conditions like macular degeneration, cataracts, glaucoma, and diabetes. Some develop vision loss after eye injuries or from birth defects.
There are many ways that eye diseases can affect vision. Depending on the cause of vision loss, symptoms can range from hazy or foggy vision, sensitivity to light, and distorted or wavy vision. Lighting conditions and daily variations can occur causing one to have “good days and bad days” with their vision. Additionally, patients report “come & go” or “now I see it, now I don’t” vision. This is because they are experiencing a blind spot in their vision. For all of these reasons, activities such as reading, shopping, cooking, seeing the TV, and writing can seem challenging.
