Which factor is NOT typically considered in lens selection?

Customer's fashion preferences are not typically a primary factor in lens selection. When selecting lenses, the main considerations are often focused on the optical performance and functional needs of the customer. Visual acuity is crucial because it determines the prescription strength required for the lenses to correct the customer's vision properly. The weight of the lenses is also important, particularly for comfort and wearability, especially for individuals who may wear glasses for extended periods. Lens coating preferences can significantly impact the overall functionality and durability of the lenses, addressing concerns like glare reduction, scratch resistance, or blue light filtering. While fashion may play a role in frame choice, the essential factors for lens selection prioritize vision correction and comfort.
