This means that these lenses are designed with particular curvatures and refractive properties that allow them to alter the path of light to correct refractive errors in the eyesight of individuals.

This definition aligns with the purpose of ophthalmic lenses, which is to provide necessary vision correction. The presence of spherical and cylindrical values indicates that these lenses can address both nearsightedness (myopia) and farsightedness (hyperopia), as well as astigmatism. The inclusion of prismatic value further extends their functionality, as these lenses can also aid in binocular vision issues.

In contrast, while other options describe different types of lenses, they do not embody the complete definition set forth in the Optometric Practice Act. For example, stating that a lens is simply any optical device for vision correction is too broad and encompasses many items that do not meet the specific criteria of an ophthalmic lens.
