Another reason to butt out. Smoking is the number one modifiable risk factor for age-related macular degeneration (AMD). So, smoking can cause blindness. In fact, AMD is the leading cause of vision loss in the Western World and 8 million Americans either have AMD or are at high risk of developing AMD.
To put this into perspective. There are 200,000 people currently living with lung cancer in the US (158,000 die of it each year).
We all know that smoking causes lung cancer but not many people are aware that it can also cause AMD and vision loss.
