It's never too late to quit smoking and save your vision (USA)

It's never too late to quit smoking and save your vision (USA)"Just in time for New Year's resolutions, a UCLA study finds that even after age 80, smoking continues to increase one's risk for age-related macular degeneration (AMD), the leading cause of blindness in Americans over 65. The American Journal of Ophthalmology publishes the findings in its January edition. 'The take-home message is that it's never too late to quit smoking,' said lead author Dr. Anne Coleman, professor of ophthalmology at the Jules Stein Eye Institute at UCLA. 'We found that even older people's eyes will benefit from kicking the habit.' AMD causes progressive damage to the macula, the center of the retina that allows us to see fine details. When the macula degenerates, people experience darkness or blurring in their central vision, preventing them from being able to read, drive and recognize faces. After age, smoking is the second most common risk factor for AMD. This study sought to determine whether age influences the effects of smoking on AMD risk"
