Optometry is a field of medicine in which the individual cares for the eyes. An optometrist studies vision and the best way to correct vision problems.
Optometry schools provide students with a science background, so that they are able to understand how a patient's overall health can influence vision problems. There are for example, many diseases which include eye problems as a symptom. For example, eye twitches can be caused by multiple sclerosis and an optometrist may be able to identify the presence of the disease first, because vision problems may be the first symptom present.
Optometry jobs are varied and multi faceted. Many that graduate from optometry school work in a practice with other optometrists to conduct vision tests and prescribe vision correction materials, such as eyeglasses. However, an optometrist can also work in hospitals, schools and facilities which conduct research. In fact, research is vital to the field of optometry so that patients can have access to better procedures and equipment.
An optometrist can work with patients to conduct vision testing, prescribe eyeglasses and contacts as well as perform minor surgeries. However, when patients require surgery, they are often refered to an opthamologists. Both an optometrist and an opthamologist are able to help patients to correct their vision.
