If a lens is stated to have a "steep fit," what does that imply?

When a lens is described as having a "steep fit," it indicates that the curvature of the lens is tighter against the curvature of the eye, particularly the cornea. A steep fit implies that the base curve of the lens is more pronounced, resulting in the lens adhering more closely to the surface of the eye.

This type of fit can be beneficial in certain situations, as it helps in stabilizing the lens for activities that involve head movements or blinking. However, it's essential to monitor such fits carefully, as an overly steep lens can restrict natural tear exchange and may reduce comfort for the wearer.

The other options do not accurately represent the implications of a steep fit. For instance, stating that the base curve is too flat incorrectly misrepresents what a steep fit means, as this description would suggest the opposite. Additionally, while oxygen transmission may be influenced by the overall design of the lens, it does not inherently correlate to the steepness of the fit. Lastly, thickness of the lens is not related to how steeply it fits; instead, this characteristic is determined by lens design and materials.
