Eye anatomy

The eye is the major sensory organ involved in vision. Light waves are transmitted across the cornea and enter the eye through the pupil. Learn more about the structure and function of the eye.

Eyewear and eye safety

Eyewear such as glasses and contact lenses corrects vision, and protective eyewear guards the eyes from injury. Related topics include contact lens care and safety, contact lenses for children, routine eye care and eye safety for children in sports.

Vision and vision loss

Vision is how the eyes and brain turn light into sight, in children and adults alike. Vision loss ranges from low vision and blindness to color blindness, and Charles Bonnet syndrome can make people with vision loss see things that aren't there. Duane syndrome limits how the eyes move.

Eye diseases and disorders

Some eye problems are minor and go away, while others can cause vision loss or blindness. Learn about the most common diseases of the eye and why early detection is key for healthy vision.

Eye disease treatment

Eye disease treatment includes surgery to correct vision or to repair the eye. Options include LASIK and phakic intraocular lenses for refractive errors, corneal transplants, vitrectomy for problems with the retina and vitreous, and laser photocoagulation for diabetic eye disease.

Eye cancer

Eye cancer is rare. Learn about symptoms, treatments and the different types, including retinoblastoma. It most often affects young children.

Eye health in specific populations

Eye health needs change across life, and some eye conditions belong to one stage of it. In newborns and children they include retinopathy of prematurity, pink eye in newborns and cerebral visual impairment; in older adults, cataract and macular degeneration.
