What might be a consequence of a lens that is too steep?

When a lens is too steep, it doesn’t align properly with the natural curvature of the eye, which can lead to decentration. This occurs because the steep curvature can cause the lens to sit unevenly on the cornea, often pushing the lens more towards the inferior and nasal positions. Decentration affects visual acuity since the optical center of the lens may no longer align with the visual axis of the eye, resulting in inferiorly and nasally displacement.

This misalignment can also lead to discomfort and more movement of the lens during blinking, which can further exacerbate the problem. Understanding the fit of a contact lens and its relationship with corneal curvature is crucial for achieving optimal visual performance and patient comfort.
