Smoking and sight loss

"The link between smoking and the UK's leading cause of sight loss is as strong as the link between smoking and lung cancer.

Smoking causes harm to the tissues of the eye. Research has confirmed the harmful effects of smoking on eyesight, particularly in the development of age-related macular degeneration (AMD) - one of the UK's leading causes of sight loss - and cataracts. "
