Which of the following is a task of an optometrist?

The task of prescribing corrective lenses is a fundamental responsibility of an optometrist. This role involves determining the appropriate prescription based on a comprehensive eye examination, which assesses visual acuity, refractive errors, and overall eye health. Optometrists are specifically trained to assess how different lenses can correct vision problems such as myopia, hyperopia, astigmatism, and presbyopia. By analyzing the patient's visual needs and personal circumstances, they can recommend the best lens options, whether glasses or contact lenses, to enhance visual performance and comfort.

While other choices may involve the eye and vision care field, they are typically roles performed by other specialists. For instance, performing surgical procedures is primarily within the purview of ophthalmologists, who are medical doctors trained to perform eye surgery. Fitting prosthetic eyes is a task often carried out by ocularists or specialists trained specifically in this area, while evaluating double vision may also fall under the skill set of both optometrists and ophthalmologists, but prescribing corrective lenses is distinctly a core competency of optometrists.
