Which of the following is a type of multifocal lens design?

The choice of aspheric as a type of multifocal lens design is appropriate because aspheric lenses, unlike traditional spherical lenses, have a gradually changing curvature that can provide a smoother transition in optical power. This is particularly beneficial in multifocal lenses, which are designed to assist individuals in seeing clearly at various distances (near, intermediate, and far). The aspheric design allows for a wider field of vision and reduces distortion that can sometimes occur with standard spherical lenses.

In contrast, the other options—myopic, hyperopic, and astigmatic—refer to types of refractive errors rather than lens designs. Myopic lenses are intended to correct nearsightedness, hyperopic lenses are designed for farsightedness, and astigmatic lenses correct for astigmatism. Therefore, while these terms relate to vision correction, they do not describe multifocal lens designs, making aspheric the accurate choice for this question.
