Very good teacher

[@fatentawalbeh1327]

thank you sir
there is a confusion with the terms of vertex, apex
some say that apex is same of optical center and it is temporal to the pupil center and the angle between the vertex and apex is angle alpha
please can you simply solve this confusion
thank you

Apex is different from visual axis and both are different from vertex.
