Smoking can cause you to develop cataracts and increases your risk for developing macular degeneration. People who smoke, have a poor diet and drink alcohol are prone to an optic nerve condition that can produce profound vision loss. Smoking is also a major irritant to patients with dry eye syndrome.

I am a girl, but I once wallowed in smoking and drinking which hurt me a lot. And now my vision and health become worse and worse that my private docotr recommended to prescribe a pair of eyeglasses to correct it. how pity it is now. And I found so many information here said I can buy one online. Is it safe? how to buy it?
