Q. I am short-sighted, 50, and need two pairs of glasses. I can’t bear the thought of bifocal glasses. Is there any alternative? A. Certainly. Contact lenses and reading glasses.,

Q. I am long-sighted, 45, and beginning to have pr^oblems reading. Also, my distance vision is sometimes a little blurred. Do you recommend contact lenses?

A. Yes. They should solve all your problems for a number of years. Eventually, of course, you will need reading glasses as well as contact lenses, but you will be spared bifocals. Read the rest of this entry »

Eventually everyone experiences presbyopia. This is the normal aging process of the eye, which begins around the age of forty for most people, and is caused by the gradual loss of elasticity in the natural crystalline lens of the eye. The lens loses its ability to change shape the way it used to, and fails to bring the light rays of near objects into sharp focus. Of course a nearsighted person over the age of forty can see near objects clearly with the naked eye, but will have difficulty doing so if he is wearing glasses or contact lenses that correct his myopia.

“I had a lot of friends who wore hard contact lenses; in fact, I’d had a brief fling with them myself about ten years ago. But I live in a big city and couldn’t stand the pain every time a little piece of dust or soot got between my cornea and my lens. So I gave up. I don’t know how my friends continued to put up with it. Actually, some of them didn’t—gradually more and more of them began switching to the (then) new soft lenses: They seemed so happy with them. . . . They finally talked me into trying again. And, boy, am I glad they did! From the very first time I wore them they were unbelievably comfortable. I barely knew that they were there. They were so easy to wear, it was all I could to to keep myself from exceeding the hours specified in my wearing schedule. That was quite a switch from my hard-lens days, when I could hardly wait to get home to take them out. Now I wouldn’t dream of going back to wearing glasses or hard contact lenses. I feel so free and I can see much better too. I’m only sorry that I waited so long.” Read the rest of this entry »

Contact lenses float on a layer of tears that covers the cornea and are held in place by surface tension. Soft lenses ride on a thinner layer of tears than hard lenses. The front and back surfaces of contact lenses serve different functions. The back surface is designed to fit the contour of the cornea itself as closely as possible to make the lens fit comfortably and, in the case of a hard lens, to provide a new, round, smooth surface. The front surface is designed to fit your prescription, which corrects your refractive error. How well your eyes are examined and measured, and how closely the contact lenses‘ size, fit, and shape come to these measurements are, therefore, very important factors in how successfully you’ll be wearing your lenses. Everything is done with highly sophisticated and accurate optical instruments, in combination with a contact lens practitioner’s experience and knowledge. Read the rest of this entry »
