I didn't mean just colour tinted specs matey. I mean the glasses that enhance the light and contrast. On a really dull grey day you put these on and it looks like a bright Summer's day. They are really amazing.
that's a good call actually, after my op's i was recommended "serengeti" sunglasses by the optician my consultant sent me to. they are anti glare and super contrast, excellent for driving/shooting and picking out detail, hope this helps a bit.
