Hello dear readers! I decided to share with you news, which became a sensation recently. The fact that a group of US scientists has found that cigarettes can cause vision loss. The study took place at Rutgers University. Pathological changes in the eyes occur when smoking more than 20 cigarettes per day.

The remaining 71 people did not smoke. The age of the subjects was 25 to 45 years. At the beginning of the experiment they were not told what it is and that cigarettes can cause loss of vision, so they led a normal life. People who smoked a lot of smoke continued.
