Studies show a strong link between smoking and the development of Age-Related Macular Degeneration (AMD), a condition that primarily affects the part of the retina responsible for sharp central vision. AMD is a leading cause of blindness in older adults and has no cure.
Some vision problems must be identified and corrected before a child reaches grade school otherwise it may not be treatable later in life. PBNC vision screens 25,000 preschoolers annually. The $20 it takes to screen one child is minimal compared to the steep cost of visual impairment over a person's lifetime.
