What is one benefit of using a thicker lens for managing mild corneal astigmatism?

Using a thicker lens for managing mild corneal astigmatism can provide less movement on the cornea. When a lens is thicker, it typically has a greater overall weight and surface area, which can help stabilize the lens on the eye. This stability is particularly beneficial for individuals with astigmatism, as it reduces the likelihood that the lens will shift or rotate during blinking or eye movement. This stability contributes to consistent visual acuity and allows for a more comfortable experience for the wearer by ensuring that the corrective optics remain aligned with the visual axis of the eye.

In contrast, while better light transmission, more eye comfort, and increased oxygen permeability are important aspects of contact lens design, they do not specifically correlate with the benefits of using a thicker lens in the context of managing mild corneal astigmatism.
