According to the American Optometric Association(AOA), children are more at risk from damaging sunlight because the lens on their eyes allows unfiltered light to reach the retina at the back of the eye. Most of us acquire over 70% of light vision damage before 18 years of age because from birth to the late teen age years the lens of the eye has no protection and both ultraviolet and Blue Light pass unfiltered through the lens of the eye.
