Why is it possible to simplify the number of actual refractions in a lens down to one refraction at a central line through the optical centre?
There are a few reasons why it is possible to simplify the number of actual refractions in a lens down to one refraction at a central line through the optical centre. One reason is that when light passes through a lens, the lens refracts the light in such a way that the light is brought to a focus. The amount of refraction that occurs depends on the curvature of the lens and the index of refraction of the lens material. However, no matter how curved the lens is, the amount of refraction is always the same at the optical centre of the lens. This is because the optical centre is the point on the lens where the light rays passing through the lens are parallel to the principal axis of the lens. Another reason why it is possible to simplify the number of actual refractions in a lens down to one refraction at a central line through the optical centre is that when a lens is rotated about its optical axis, the image formed by the lens does not rotate. This is because the optical centre of a lens is invariant with respect to rotation. This means that it is not necessary to take into account the actual refractions that occur at different points on the lens when calculating the image formation by the lens.
Where is the optical center of a Kryptok 22 lens?
It's in the centre of a round segment!
When a ray of light passing through a point in a lens does not undergo deviation?
When it passes through optical centre.
Why the a ray passing through center of lens do not bends?
It is because the central portion of the lens i.e. optical centre can be considered similar to a parallel sided glass slab.
What lens Has an optical axis?
If you are talking convex and concave, they both have an optical lens. Sorry if that doesn't help, but what do I know.

What is optical center of a lens?
optic centre is the geometrical centre of the lens the rays of light passing through this point emerges in the same direction without bending.
What is called optical center of a lens?
optic centre is the geometrical centre of the lens the rays of light passing through this point emerges in the same direction without bending.
What is optical center of lens?
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.
When a ray of light passing through a point in a lens does not undergo deviation?
When it passes through optical centre.

It is because the central portion of the lens i.e. optical centre can be considered similar to a parallel sided glass slab.
Does a thinner and less convex lens have a shorter focal length and low optical power?
It is not necessary that a thinner convex lens have less optical power or a thicker lens has more optical power

What is optical energy?
Optical Energy, better known as Optical Power, is the converging strength of a lens. As an example a lens with a high Optical Power will have a wider range of view but less focal distance. A lens with low Optical Power will have a longer focal distance but less range of view.
Differentiate convex lens from concave lens?
A convex lens is thicker in the centre than the outsides. A concave lens is thinner in the centre than the outsides.
What is the optical center of a zoom lens?
If you look through the lens at a distant point, the point image will not move when the lens is rotated slightly about a vertical or horizontal axis the goes through the nodal point. This is called the optical center. With a thin lens this is close to the geometric center, with a longer complex lens the optical center is buried somewhere inside. The optcial center of a complex lens may or may not be inside an element.
