What is the first step an optician takes when fitting corrective eyewear?

Measuring the member's facial and eye measurements is a critical first step for an optician when fitting corrective eyewear. This process ensures that the glasses will not only be comfortable but also provide the best possible vision correction. Accurate measurements, such as the distance between the eyes (pupil distance), the size of the frames that will fit the individual's face, and the angle at which the glasses sit, are essential to ensure that the lenses are positioned correctly for optimal visual acuity.

This initial assessment lays the foundation for selecting the appropriate lens type, style, and frame that suit the individual’s needs, personal preferences, and aesthetic choices. Without these measurements, the optician cannot effectively interpret the prescription or assist in the selection of lens styles, as the fit directly impacts the lenses' performance. While performing eye examinations is essential for determining prescription strength, it typically occurs prior to the fitting process and is therefore not the first step in fitting corrective eyewear.
