Certified Paraoptometric (CPO) Practice Exam 2025

Aspheric lenses are noted for having which of the following characteristics?

1. A wider field of view and thicker lens profile

2. A wider field of view and thinner lens profile

3. A narrower field of view and thicker lens profile

4. A narrow field of view and standard thickness

The correct answer is: A wider field of view and thinner lens profile

Aspheric lenses are designed to have a more complex surface profile compared to traditional spherical lenses. This unique contour allows for several benefits, among which is the ability to provide a wider field of view. This characteristic is particularly beneficial for individuals with higher prescriptions, as it minimizes distortion and provides clearer peripheral vision. Additionally, aspheric lenses are typically thinner than their spherical counterparts at the edges, especially for higher prescriptions. The design reduces the overall weight and bulk of the lens, enhancing comfort for the wearer. Therefore, the correct choice accurately reflects that aspheric lenses offer both a wider field of view and a thinner lens profile, making them a preferred option for many patients seeking improved visual quality and comfort.
