What is the primary purpose of an eye exam in the Costco Optical Department?

The primary purpose of an eye exam in the Costco Optical Department is to assess vision and detect eye health issues. During an eye examination, various tests are conducted to evaluate visual acuity, check for refractive errors such as nearsightedness or farsightedness, and screen for common eye conditions including glaucoma, cataracts, and macular degeneration. This comprehensive approach ensures that both the quality of vision and the overall health of the eyes are thoroughly assessed.

While prescribing medications for eye diseases is a critical function typically carried out by specialized eye care professionals, it is not the main focus of routine eye exams conducted in a retail optical setting like Costco. Similarly, color blindness evaluation is an important aspect of vision assessments but is only a subset of the broader evaluation of one's overall vision and eye health. Providing vision therapy falls under specialized treatments often managed by optometrists or ophthalmologists, not a standard component of a routine eye exam. Hence, assessing vision and identifying potential eye health issues stands out as the central aim of the procedure in this context.
