As we age, our eyes change in several ways that make vision less clear. Many of the changes are unavoidable, but, since excessive light exposure is known to accelerate cataract formation and to damage the retina (both of which occur with aging), we should at least try to slow these effects of aging as much as possible by regularly wearing proper sunglasses whenever we are outdoors.
Another thing that we can do to help ourselves is to have eye tests regularly for glaucoma, a condition that becomes more likely if we take certain medicines, including antihistamines, cough medicine, some types of sleeping pills, antidepressants, and drugs for dizziness or Parkinson’s disease, Postgraduate Medicine (81#2:108) reports. These medications do not cause glaucoma but can aggravate it if it already exists. Furthermore, since these medicines are often essential, never discontinue them on this account without a doctor’s orders. If you are taking one of these medicines, regular glaucoma testing is especially important.
