The most common types of refractive errors are myopia, hyperopia, presbyopia, and astigmatism myopia (nearsightedness) is a condition where objects up close appear clearly, while objects far away appear blurry. Refractive index is defined as the ratio of the speed of light in a vacuum to that in a given medium. The effective refractive index is a number quantifying the phase delay per unit length in a waveguide, relative to the phase delay in vacuum.
