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 rays away from the center
Rainbows are related to physics through the lens effect of water drops. Water in the atmosphere acts as a lens and bends sunlight passing through the drops producing the colors of the rainbow. Newton demonstrated this lens effect, demonstrating that "white light" was composed of colored light.
frikin question answer=blah blah blah hahahaha....lol...!
A convex lens is wider at the edges than it is in the center. Therefore, it is a converging lens.
It bends light.
concave lens bends light rays away from the center
It bends the rays light which pass through it.
No it do not bend.
optic centre is the geometrical centre of the lens the rays of light passing through this point emerges in the same direction without bending.

a lens works when light goes through it and refracts (bends) inside the lens. so the light
The optical center of the lens is a point on the axis of a lens is the point where any ray passing through this point, the incident part and the emergent part are parallel. It is important for the proper refraction of light.

The crystalline lens is the part of the eye that bends/refracts the light rays as it passes through it.

Any incident ray traveling parallel to the principal axis of a converging lens will refract through the lens and travel through the focal point on the opposite side of the lens.Any incident ray traveling through the focal point on the way to the lens will refract through the lens and travel parallel to the principal axis.An incident ray that passes through the center of the lens will in effect continue in the same direction that it had when it entered the lens.
Theoretically is undeviated.
