How to Read Your Glasses Prescription?Many students like to exam their eyes and buy eye glasses. Because they know little about glasses prescription related technical terms, every glasses term is difficult to understand, so I will talk about how to read prescription glasses. Knowing how to read an eyeglasses prescription can be useful in the event you need to buy new eyeglasses, replace missing or broken glasses. Prescription glasses are more difficult to understand: OD indicates the right eye, OS left eye; “+” for hyperopia, “-” for myopia; the arab value after “+” or “-” means refraction lens. DS means spherical (myopia and hyperopia with), DC means column mirror (astigmatism use); PD means the distance between the pupil. If you know the above basic knowledge, I am sure you will buy a pair of quality prescription glasses very easily.
