Refraction Simplified for the Post Graduates
The optics of the eye normally creates a clear image by refracting rays of light to focus on the retina. Imperfections in this optical system create aberrations and thus blurred images. The goal is to analyze them and devise a means to eliminate them. Lower order aberrations are primarily refractive errors when parallel rays of light after refracting, do not focus on the retina with accommodation ...Read More
