Are you worried about losing sight? This is what you can do to protect yourself

Many people think that vision loss with age happens automatically, but this is not true. Several studies have found that smokers are 2 to 4 times more likely to develop macular degeneration, compared to people who have never smoked a cigarette. If left untreated, vision loss can lead to cognitive decline and even dementia, because as you might imagine, poor vision limits participation in physical and social activities, which are important for preventing dementia.
