What is the primary function of an optometrist?

The primary function of an optometrist is to perform eye examinations and assess vision, which encompasses fitting contact lenses. Optometrists are trained to evaluate how well a person can see and identify vision issues, prescribing glasses and contact lenses as necessary. Notably, while they do provide treatment for some eye conditions, their primary role focuses on vision care and correction, which includes the fitting of contact lenses to help patients achieve optimal eyesight.

Fitting eyeglasses is also part of an optometrist's role; however, the option that encompasses a broader aspect of their specialty, including a focus on modern vision correction methods like contact lenses, makes the second option—fitting contact lenses—the best representation of their primary function.

Although optometrists can advise on treatment for minor eye conditions, they typically do not perform surgery, which is usually reserved for ophthalmologists, and their involvement in treating serious eye conditions happens within certain limits, reinforcing their primary function as that of vision care rather than surgical intervention.
