Low vision affects people at school, on the job, and at home. It makes daily activities like writing, reading, watching television, and walking difficult. Symptoms of low vision include:
Where objects appear out of focus. Causes include macular degeneration, diabetes, corneal disease, and cataracts.
A darker hazy patch appears in the center of objects. Causes include macular degeneration and optic atrophy.
Objects blend with background: lights are distracting or uncomfortable. Causes include glaucoma, cataracts, corneal disease, and albinism.
Dark patches are scattered around objects. Causes include diabetes, glaucoma, retinal detachment and trauma.
Objects appear out of shape, crooked, deformed, wavy, or doubled. Causes include macular degeneration, diabetes, and retinal detachment.
Objects in the center of the field of vision are visible: objects on the sides are missing. Causes include glaucoma, retinitis pigmentosa, and stroke.
