It is because the central portion of the lens i.e. optical centre can be considered similar to a parallel sided glass slab.
Concave lens bends light inward. It is thinner at the center and thicker at the edges, causing light rays passing through it to diverge.
No, concave lenses cause light rays to diverge outward when passing through them. This is due to the lens being thinner at the center than at the edges, causing light rays to spread out.
Light bends when passing through a lens due to refraction, which is the change in speed and direction of light as it travels from one medium to another. The shape of the lens causes the light rays to converge or diverge, focusing the light to create an image.
This type of lens is called a convex lens. It is thicker at the edges and thinner in the center, causing light rays passing through it to bend outward. Convex lenses are commonly used in cameras, eyeglasses, and magnifying glasses to focus light and produce images.

A concave lens bends light away from its center, diverging the light rays.
A convex lens is thicker in the center than at the edges. A convex lens is like a concave mirror.A concave lens is thinner in the center than at the edges.
Light passing through the optical center of a lens does not deviate in direction.
A concave lens causes light rays passing through it to diverge. This is because the lens is thinner at the center than at the edges, causing the light rays to spread out.
The blank you are referring to is the focal length of the lens. It is the distance from the center of the lens to its principal focus, where parallel rays of light converge after passing through the lens.
The optical center of a lens is a point on the lens axis where light passing through the lens does not deviate, regardless of the angle of incidence. It is often used as a reference point for optical calculations and design. The optical center is typically at the geometric center of a lens with a symmetrical shape.
The amount of bending of light passing through a lens can be controlled by changing the curvature of the lens surface. A flatter lens will cause less bending, while a more curved lens will cause more bending. The material of the lens and the wavelength of light can also affect the amount of bending.
