Example text

Why do I keep needing stronger glasses every time I come in, and why can’t I see as well without my glasses? This question is usually asked by someone who is hyperopic, or farsighted. ) As your focusing system, which involves your ciliary muscles, begins to lose its ability to “accommodate” for reading, it also becomes less able to compensate for your hyperopia. If you’re farsighted, you’ve probably been using these ciliary muscles all your life to compensate for this relative eye weakness. Because of this, when you’re younger the ciliary muscles tend to stay somewhat contracted; as a result, any early eyeglass prescriptions you may have are weaker than you might need if these muscles were fully relaxed.

Then along comes presbyopia—and this plus changes in lid tension across the cornea can cause changes in astigmatism that may be for better or worse, depending on your particular case. Early cataract formation can also cause changes, as the cataract subtly changes the shape of the lens within the eye. Aging and Presbyopia After its onset, presbyopia produces a classic pattern of change over the next fifteen to twenty years. Initially your glasses prescription is doing part of the focusing for you.

The term accommodation refers to the way the eye muscle and lens work together to focus on something nearby—a book, for example, or a makeup mirror. Farsighted people use this same accommodative system to compensate for their lack of focusing power, in order to see at a distance. When farsighted people try to read, however, they must focus for their hyperopia as well as for the reading distance—an effort that requires significantly more eye muscle power. For farsighted people, then, vision is relatively clearer at a long distance than up close, because it takes less muscular effort.
