What adjustment is made in the prescription to limit distortion for individuals with significant refractive errors?

• A. Increasing add power
• B. Using aspheric design
• C. Thicker lens material
• D. Decreasing the base curve

Answer: (B)

Using aspheric design is the correct adjustment to limit distortion for individuals with significant refractive errors. Aspheric lenses are specifically designed to have a gradual change in curvature, which helps to reduce spherical aberration and provides a wider field of vision. This design is particularly beneficial for people with high prescriptions, as it allows for a thinner and lighter lens profile while improving optical performance. Aspheric lenses minimize the distortion that can occur at the edges of traditional spherical lenses, which often affects visual clarity. This design enhances the overall quality of vision, making it particularly advantageous for those with significant refractive errors who may experience more pronounced visual distortions with conventional lens designs. The benefits of aspheric lenses make them a preferred choice for correcting higher degrees of myopia, hyperopia, or astigmatism, ultimately providing a more comfortable and effective visual experience.
