	Vision Impairment (part 1), NCBDDD, CDC
		Vision impairment may be caused by a loss of visual acuity, where the eye does not see objects as clearly as usual.
		Impaired vision can affect a child’s cognitive, emotional, neurological, and physical development by possibly limiting the range of experiences and the kinds of information a child is exposed to.
		It includes goals related to vision impairment, such as preventing eye injuries, increasing the number of people who have their eyes examined, decreasing the number of children under 17 years old who are blind or visually impaired, decreasing the number of people who lose their vision due to diabetes, and others.

	Low Vision Defined - Lighthouse International
		Vision is a complex sense, encompassing the ability to perceive detail (acuity), color and contrast, and to distinguish objects.
		Low vision services are provided by specially trained professionals in a number of settings: hospitals, vision rehabilitation organizations, private optometric and ophthalmologic practices, and educational and university facilities.
		The adaptive process, in coordination with low vision services, is known as vision rehabilitation; its goal is to equip people who are visually impaired with the skills and confidence needed to function as independently as possible.

		Low Vision is a bilateral impairment to vision that significantly impairs the functioning of the patient and cannot be adequately corrected with medical, surgical, therapy, conventional eyewear or contact lenses.
		It is often a loss of sharpness or acuity but may present as a loss of field of vision, light sensitivity, distorted vision or loss of contrast.
		Low Vision Specialists are licensed Doctors of Optometry or Ophthalmology, who are skilled in the examination, treatment and management of patients with visual impairments not fully treatable by medical, surgical or convention eyewear or contact lenses.

	Science News: Slowing Macular Degeneration with Antioxidants
		For reasons that have yet to be understood, sometimes the light-sensitive cells in the macula break down, resulting in a loss of central vision.

		The retina becomes diseased, leading to the slow breakdown of the light-sensing cells in the macula and a gradual loss of central vision.

	Macular Degeneration
		There are a number of abnormalities associated with the term "age-related macular degeneration." They range from mild changes with no decrease in vision to abnormalities severe enough to result in the loss of all "straight ahead" vision.
		Vision may also be affected when there are disturbances in the layer of cells below the retina called the retinal pigment epithelium.
		In an effort to detect loss of vision associated with macular degeneration, eye doctors across the country are recommending this test to their patients.
