A light ray refracts as it enters a piece of glass because the speed of light changes as it moves from one medium (air) to another (glass), causing it to bend. This change in speed is due to the difference in the optical density of air and glass, which causes the light ray to change direction at the boundary between the two mediums.
Lens.
When light passes through a flat piece of glass, like a window, the light is refracted at both surfaces, but the exiting ray of light is parallel to the entering ray and hence the light's path is not really changed.
The curvature of a lens causes incoming light to bend or refract at different angles, focusing or diverging the light rays to create images. This bending is due to the varying thickness of the lens, which changes the speed of light passing through it. A flat piece of glass does not have the same effect on light because it does not cause the same degree of refraction or focusing.
A piece of glass with one or two spherical surfaces is called a lens. Lenses are commonly used in optics to refract light and focus images.
A lens is a curved piece of glass or transparent material that is designed to refract (bend) light rays, focusing them to create an image. Lenses are commonly used in cameras, eyeglasses, microscopes, and telescopes.

The speed of light slows down ... in general, the denser the material, the lower the speed of light. (For example : air to water to glass.) The maximum speed is in a vacuum.
