The principal advantage of a minus carrier contact lens for high hyperopes lies in its design, which typically allows the lens to center better on the eye. In the case of high hyperopia, where there is a significant refractive error, a minus lens has a thinner center relative to the edges because it is designed to diverge light. This thinner center facilitates better positioning on the cornea, leading to improved centration during wear.

Centration is crucial for ensuring optimal visual acuity, as well-centered lenses provide more stable vision and less distortion. If a lens is off-center, it can lead to discomfort and compromised visual performance, particularly in the peripheral vision. Therefore, the advantageous design of the minus carrier lens aids in promoting a proper fit and alignment on the eye, enhancing the overall user experience for individuals with high hyperopia.

Other aspects like masking corneal astigmatism, ease of insertion, and reducing lens movement may also apply in certain contexts, but they do not directly address the critical benefit of improving lens centration for this specific population of patients.
