Rays of light that pass through the lens are brought closer together (they converge). A convex lens is a converging lens. When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus. The distance between the principal focus and the centre of the lens is called the focal length.

#### Focal Point - Convex Lenses - CBakken

A convex lens has two focal points - one on each side. They are equal distances from the lens. The lens does not have to have the same curvature on both sides for this to be true, and it doesn't depend on the direction the light takes entering the lens. It is the combined curvature that determines the focal point.

#### Tiny Convex Lenses - Some Physics Insights

I. On-Axis Behavior of a Small Convex-Convex Lens As we have also noted elsewhere, a single surface lens cannot be ideal no matter what "figure" it has. In this section we will find that, in contrast, a tiny symmetric lens, with two convex surfaces, acts as an ideal lens for rays entering nearly on-axis. Consequently, a small, thin lens will image a distant scene the same way an ideal lens would.
