If you need clear lenses for winter or night time then the clear with the slight tint will work fine, or if you want to jazz up the style then you have the Revo Red and Revo Green, which in addition reduce glare or maybe the the standard grey suits.
In addition why not have Yellow Lens sunglasses which heightens contrast in overcast, hazy, low-light conditions outdoors or for indoor sports. Filters blue light for sharper focus. They make a overcast day seem sunny and help spot those pot holes in the road and if you are a Cricketer or Golfer it helps spotting the ball with the amber lenses
In addition Skiers will find the yellow lenses will show up the undulations in the snow.
NB even the clear give UVA 400 protection, which is down to the poly-carbonate material which the lenses are made from.
