■COMMENT
#This POWDERHORN was made in 1970s.
#"BL" etchings on both lenses but lie horizontally Not vertically like many vintage Ray-Ban made after 1980s.
#Ambermatics is for all weathers, which is one of the most unique lenses ever made. It combined photochromic capabilities to change density depending on the degree of both brightness and temperature. It would change from amber yellow to grey and get even denser (got darker to block more light) in cold bright environments.
#This DGM (Double Gradient Mirror) lenses have the coating applied to the top and bottom areas of the lenses to protect against overhead reflected glare. The coatings are graduated in density, becoming gradually heavier from the center toward the top or bottom of the lenses. So DGM is recommended for snow or water sports.
#B&L Ray-Ban Mirror lenses are available in 3 forms: Full Mirror, Double Gradient Mirror and Top Gradient Mirror.
