Increasing the base curve of a lens generally leads to an increase in the size of the image formed by the lens. This is due to the optical characteristics of curved lenses. When the base curve is increased, the lens becomes steeper, which enhances its optical power. This optical power affects how light rays converge or diverge after passing through the lens.

As the lens curvature increases, the focal length typically decreases, meaning the lens can project a larger image of the object being viewed, impacting the perception of size. A steeper curve allows for more significant bending of light rays, leading to a larger apparent image.

Conversely, in scenarios where base curve alterations lead to distortions in vision or changes in the optical path, such as certain types of lens designs or materials, those factors could lead to perceived diminishment or distortion rather than outright increase in size. However, when specifically considering the relationship between base curve and image size, increasing the base curve directly corresponds to an enhancement in image size under usual circumstances.
