Vision

Goal

Improve the visual health of the Nation through prevention, early detection, timely treatment, and rehabilitation.

Overview

Vision is an essential part of everyday life, influencing how Americans of all ages learn, communicate, work, play, and interact with the world. Yet millions of Americans live with visual impairment, and many more remain at risk for eye disease and preventable eye injury.

The Healthy People 2020 Vision objectives focus on evidence-based interventions to preserve sight and prevent blindness. Objectives address screening and examinations for children and adults, early detection and timely treatment of eye diseases and conditions, injury prevention, and the use of vision rehabilitation services.

Why Is Vision Health Important?

The eyes are an important, but often overlooked, part of overall health. Despite the preventable nature of some vision impairments, many people do not receive recommended screenings and exams.1 A visit to an eye care professional for a comprehensive dilated eye exam can help to detect common vision problems and eye diseases, including:

  • Diabetic retinopathy
  • Glaucoma
  • Cataract
  • Age-related macular degeneration (AMD)

These common vision problems often have no early warning signs. If a problem is detected, an eye care professional can prescribe corrective eyewear, medicine, or surgery to minimize vision loss and help a person see his or her best.

Healthy vision can help keep people safe when behind the wheel, participating in sports, or working with power tools in the yard or around the home. It can also help to ensure a healthy and active lifestyle well into a person’s later years. Educating and engaging families, communities, and the Nation is critical to ensuring that people have the information, resources, and tools needed for good eye health. Resources and tools include:

  • Eye health care
  • Vision correction
  • Emerging treatments
  • Vision rehabilitation services and adaptive devices that enable people to make the most of their remaining vision and maintain an independent lifestyle

Understanding Vision Health

The need to promote and protect healthy vision continues through the entire lifespan and applies to all ethnic and racial groups. Research indicates that several diseases and eye disorders are more prevalent in certain racial and ethnic minority communities and disproportionately affect minority populations more than whites.2, 3, 4, 5

Access to Health Care

In 2005, the National Eye Institute (NEI) conducted a series of focus groups on factors that influence the receipt of preventive eye care. Participants indicated that the cost of services is prohibitive, particularly when it comes to receiving follow-up care.6

Healthy Aging

With the aging of the population, the number of Americans with major eye diseases is increasing, and vision loss is becoming a major public health concern. By the year 2020, the number of people who are blind or have low vision is projected to reach 5.5 million.7

Environmental Determinants

Eye injuries are also a major eye health concern in the United States. Each day, more than 2,000 American workers receive some form of medical treatment due to eye injuries that happen at work.8 Nearly half of all eye injuries occur at home, and more than 1 in 4 occur during sporting and recreational activities, or on streets and highways.

Emerging Issues in Vision Health

Genotyping

Researchers are capitalizing on the remarkable progress made by the Human Genome Project and the Genome-Wide Association Studies. Datasets for AMD and a twin study of risk factors for glaucoma and myopia have been added to the public domain (known as dBGap). New studies are also working to identify the relationships of environmental exposures to gene-trait associations in common, complex diseases.

Gene Transfer Therapy

Gene transfer therapy in patients with Leber congenital amaurosis—a severe, early-onset retinal disease—indicates that the treatment is safe, with evidence of lasting visual improvement. These findings could help usher gene-based therapies for other retinal diseases, such as retinitis pigmentosa and macular degeneration, into clinical trials.

Comparative Effectiveness

Investigators are conducting several comparative effectiveness clinical trials to improve ophthalmic care.

  • Laser treatment is a standard of care for diabetic eye disease, where abnormal blood vessel growth damages the retina. However, recent evidence suggests that treatment with various drugs may deliver a better outcome.
  • Researchers aim to understand the complex genetic and biological factors that cause glaucoma and to develop treatments that protect optic nerves from the damage that leads to vision loss.
  • Rehabilitation research is improving the quality of life of people with visual impairments by helping them maximize the use of remaining vision and by devising improved aids and strategies to assist those without useful vision.
