Geometric analysis of ophthalmic lens by conjugate method

摘要

This paper will show the optical models of myopia and hyperopia in geometric analysis by conjugate method (CM), named CM. The design activity of ophthalmic lens involves relatively simple, often elementary geometric optics. By CM, it gives a clear idea how the eye works as a lens to form an image of the retina. Using this simple geometric analysis, we can see the correction of ametropia eye by correction lens, i.e., spectacle, is to fulfill the needs to put the object on the conjugate of retina formed by the myopic and hyperopic eye.
