other info

• Specialist sport sunglasses, these Chromax Ace
  
  lenses were designed particularly to enhance
  
  the contrast between a target (ie golf ball) and
  
  a green background. They also have extra
  
  anti-reflective coatings to cut out back glare.
  
  At only 68% absorption they are the best in
  
  medium light conditions. The uv protection is
  
  as you would expect excellent, 99% at 400nm
  
  and of course they are glass lenses. The arms
  
  are a unique design whereby the temple tips
  
  unclip to offer a cable grip. No wonder then these
  
  retailed for £142.00 even 10 plus years ago.
  
  NB: although we found these unworn, they have
  
  picked up a couple of very small marks over the
  
  years in storage.
