Which statement correctly reflects the relationship between lens fit and comfort?

Explanation:
Comfort with soft contact lenses hinges on how well the lens sits on the eye. When a lens fits relatively tight and its base curve is closer to the corneal curvature, it tends to stay centered and move only a little with each blink. This stability reduces lid rubbing and tear film disruption, which often translates into a more comfortable wearing experience. A steeper base curve creates that tighter fit, helping the lens stay in place and minimizing edge lift or decentration that can irritate the lids or cornea. Keep in mind that there is a balance: if the fit is excessively tight, it can compromise oxygen to the cornea and cause other issues, but within an appropriate range, a snug, well-centered lens improves comfort by limiting disruptive movement and lid-lens interactions. Statements suggesting that more post-blink movement or a larger diameter automatically improve comfort don’t fit, because increased movement and ill-fitting edge effects tend to cause irritation, and comfort is indeed influenced by how the lens fits and centers on the eye.
