Which lens fitting would likely result in too tight a fit?

A lens that is too small would likely result in a tight fit because it does not adequately cover the corneal surface. When a contact lens is undersized, it can sit more snugly against the eye, leading to discomfort and potential complications such as reduced oxygen transmission or increased risk of irritation.

In the context of fitting, an appropriately sized lens should cover the entire cornea while allowing for proper movement with blinking. If the lens is smaller than optimal, it may create pressure points or fit too closely to the cornea, which can contribute to discomfort. This situation emphasizes the importance of appropriate lens measurement and selection to ensure patient comfort and eye health.

Fitting choices like a flatter base curve, oversized lenses, or those with higher water content do not inherently lead to a tight fit. Instead, they may lead to more comfortable or looser fits, depending on the unique characteristics of the patient's eye.
