If you’ve gotten glasses from our Towson opticians
here at the office of Eye to Eye, then you know what a difference they can make to your quality of life. It’s like a little miracle: One moment your squinting and straining to read the magazine in front of you, and then all of a sudden, all the words are crystal clear! What you may not know, however, are the scientific underpinnings of eyeglass lens prescriptions and fittings. Because we believe educating our patients is both fun and important to the maintenance one’s eye health and function, we’d like to tell you a little bit about the optics of visual impairment and vision correction.
Though there are obviously important differences between them, nearsightedness, farsightedness and astigmatism all stem from the same basic problem: eyes that are misshapen in such a way that incoming light is not properly focused on the backs of your eyes (a.k.a. your “retinas”). Nearsightedness, for example, occurs when images focus in front of the retina, instead of directly on it. The reason all of the conditions are referred to as “refraction errors” by our Towson opticians
at Eye to Eye is due to the fact that all three share this common cause. What eyeglasses do, then, is bend light in a way that counteracts the “mis-bending” of light by your naked eye. Because eye geometry can be warped in so many ways, figuring out just what lens a person needs is very tricky business. This is why you eye doctor spends so much time asking you, “Is this better, or is this better?” This is also why making sure you have well-fitting frames is so important. If your eyeglass lenses aren’t positioned in front of your eyes in just the right way, light won’t enter your eyes how it’s supposed to.
