Optometry is a medical profession that deals with the eyes and eye health. Optometrists can look at patients’ eyes to address abnormalities or irregularities as well as diagnose diseases of the eye. These doctors may also refer patients to surgeons who can correct eye problems. While optometrists do also focus on helping people find corrective lenses that can improve their vision, their focus extends far beyond glasses and contacts to include overall eye health, including management of eye diseases.

Sports medicine is a branch of medicine that works with athletes and others who play sports or take part in physically demanding activities that may result in injury or other overuse-related problems. Therefore, it is closely related to physical therapy. Since athletes can experience certain issues that may be uncommon in the rest of the population, the doctors who specialize in this field have advanced knowledge of the body and issues that may arise from participating in various physical activities.
