Stigma is actually referring to a type of refractive error known properly as astigmatism, and no, you will not go blind from having astigmatism; it is not a disease, in fact, it is relatively common. There are three types of refractive error, myopia, hyperopia, and astigmatism. The former two are more regularly referred to as nearsighted (cannot see far away) and farsighted (cannot see up close). Astigmatism is simply the third category; it affects both the near and far vision at the same time. Much like nearsightedness or farsightedness, astigmatism is corrected using glasses or contacts. Technically speaking an eye with astigmatism requires two different prescriptions to correct vision in one eye due to the more oval shape of the cornea. This will require a more specialized contact lens and a more in-depth fitting procedure. Nonetheless, your eye care provider can, and will, correct your astigmatism with glasses and/or contacts.
