If you are a smoker, butt out! Of course, smoking will lead your eyes to yellow and the skin around them to wrinkle and thin. On top of that, smoking is linked to a high risk of macular degeneration, cataracts and even damage to the optic nerve, all of which can lead to blindness.
Quit smoking immediately. Smoking is terrible for your eyes as it will restrict the blood flow that you need to keep your eyes functioning properly. Additionally, smoking can disrupt your immune system, which is needed to flush out the free radicals in your body. This will make you feel better while improving the health of your eyes.
