Vision Loss And Blindness
Vision loss is a degree of blindness that can not be corrected with glasses or contact lenses. For many people, vision loss occurs somewhere in the middle of that spectrum, “legally blind” or “low vision.” A large percentage of individuals with vision loss aren’t completely blind. Nevertheless, vision loss occurs when a person’s eyesight is not correct for a “normal” level, and it can vary significantly among children and occurs due to many factors. However, they suffer from low vision. Therefore, low vision is a vision problem that makes it difficult to do routine and everyday activities, and it can be characterized by an extensive range from minor vision loss to complete blindness.
Globally there are over 2.2 billion people with eye and vision problems (WHO). In 2022 approximately 12 million people in the United States, aged 40 and above suffer from vision impairment, with about a million suffering from blindness. Recent eye research shows an interrelationship between foods like fish, green leafy vegetables, nuts, and berries, exercises, and good eyesight. These foods can enhance eye vision and health, and prevent age-related eye diseases Vision loss is a common part of aging and the main cause of vision loss in people older than 40 years of age. Numerous circumstances like stress, smoking, sunlight, and medication contribute to vision loss.
Vision Loss Due To Common Eye Diseases And Disorders
Vision loss occurs when there is damage to the eye itself, an incorrect eye shape, and/or a problem in the brain.

- 20/70 to 20/160– moderate visual impairment, or moderate low vision.
- 20/200 or worse – a severe visual impairment, or severe low vision.
- 20/500 to 20/1000 – profound visual impairment or profound low vision.
- Less than 20/1000 – near-total visual impairment or near-total low vision.
- No light perception – total visual impairment, or total blindness.
