Optometry
The term "optometry" comes from the Greek word optos, meaning eye or vision, and metria, meaning measurement.
The eye, including its structure and mechanism, has fascinated scientists and the public in general since ancient times. Many of the expressions in the English language that mean to understand are equivalent vision terms. "I see", to mean I understand.
Many patients when told that they may have an eye problem will be more concerned about diseases that affect vision than other, more lethal diseases. Being deprived of sight can have a devastating effect on the psyche, as well as economic and social effects, as many blind individuals require significant assistance with activities of daily living and are often unable to continue gainful employment previously held while seeing[citation needed].
The maintenance of ocular health and correction of eye problems that decrease vision contribute greatly to the ability to appreciate the longer lifespan that all of medicine continues to allow. Given the importance of vision to quality of life, many optometrists consider their job to be rewarding, as they are often able to restore or improve a patient's sight.
Behavioural optometry is a related area of non-strabismus vision therapy that some optometrists practice. Generally Ophthalmologists and Orthoptists do not practice this.
In the United States, optometrist have tried to obtain from state legislatures, the right to treat more eye conditions and to perform certain laser surgeries. Optometrists have been successful in getting the right to use some types of medication, depending on if the medication is given as pills, eye drops, or injections. In Oklahoma, optometrists are allowed by the state legislature to do certain kinds of surgery.
Optometry is a health care profession concerned with eyes and related structures, as well as vision, visual systems, and vision information processing in humans.
Like most health professions, optometry education, certification, and practice is regulated in most countries. Optometrists and optometry-related organizations interact with governmental agencies, other health care professionals, and the community to deliver eye and vision care. Optometry is one of three eye care professions, the others being Ophthalmology (which is a branch of medicine) and Orthoptics (a sub-specialty of ophthalmology primarily dealing with strabismus).
