1980's layered dark tortoise and white plastic
B&L RAY-BAN USA and BLAZER
Original B&L Ambermatic Full Mirror glass lenses
In 1978 Ray-Ban first introduced their Ambermatic lens -
a unique photochromic lens that started off an amber yellow,
darkened to golden brown in the sun yet in freezing conditions
would change again to grey. Wow.
(Here is an ad from 1978
showing the Ambermatic in a Vagabond). This is the Full Mirror
version, which looks only slightly mirrored in this amber phase,
but gets more mirrored as it darkens. Ray-Ban said the mirror
coating added, "extra glare protection to Ambermatic lenses
for snow or water sports in which intense glare is often a problem."
Blazer was part of Ray-Bans Sport Collection which first appeared
in 1980. This colourway was simply called Dark Tortoise/White,
with the white layer sandwiched between the two darker layers.
With these lenses it was Ray-Bans most expensive sunglasses,
retailing at $55, more than three times the price of the Wayfarer
at the time, which is why it is so rare to find today.
NB: the lenses have been marked down to 'good' not for any
marks on the lenses, rather it is because at the lightest point -
ie when indoors - the lenses at the top nasal corner have a lighter
area - see top photo. This is less noticeable when they darken in
the sun and not noticeable when wearing.
