Found this intersting article about people who suffer from BOTH myopia (short-sightedness) and presbyopia (long-sightedness) and what the options are.

After age 40, the single pair of glasses or contact lenses you previously wore generally will no longer give you clear vision at all distances — or at least not without some compromises. These vision problems are caused by presbyopia, which affects all of us beginning in middle age and reduces our ability to see at all distances. Many vision correction options are available, such as presbyopia surgery and multifocal contact lenses or eyeglasses. If you need cataract surgery, you also have the option of choosing multifocal intraocular lenses to restore your ability to see at all distances. In some cases, however, you may need to consider a combination of options to fully address problems caused by presbyopia.

If you are nearsighted, you have an advantage when you reach your 40s. Once presbyopia occurs, nearsighted eyes still see well up-close — if you remove your eyeglasses. Of course, with your glasses removed, distance vision is blurred. So you will need to put your glasses back on to see clearly across the room. Beginning at around age 40, you’ll find that the usual glasses or contacts you always wore will not correct focusing problems caused by presbyopia.The amount of nearsightedness you have determines how close or far you need to hold an item to see it clearly without your glasses on. If you are mildly nearsighted (with a prescription of -1.50 or -2.00 D, for example) you will see very well at a normal reading distance of 14 to 16 inches from your face. But if you’re highly nearsighted (let’s say -5.00 D or higher), you’ll have to bring items much closer to your eyes to see them clearly. If that’s the case, you may want to consider the next option.
