Optometry and Vision loss
Optometry is the field involving virtually everything that has to do with eyes and vision, including examination, diagnosis and treatment of the eyes and surrounding structures, and the treatment of vision problems.
Doctors of Optometry (ODs), commonly known as optometrists, are independent primary health care professionals for the eyes. They are trained to evaluate a patient’s visual condition and determine the best treatment for that condition.
Loss of vision is considered sudden if it develops within a few minutes to a couple of days. It may affect one or both eyes and all or part of a field of vision. Loss of only a small part of the field of vision may seem like blurred vision. Other symptoms, for example, eye pain, may occur depending on the cause of vision loss.
