I own a pair of these grey lenses and all I can say is that they're AMAZING! The colours are very natural and visible when worn and are very comfortable to wear. It had a blue-ish green undertone which blends in very well with my natural eye colour (I've got brown eyes) and I've been given so many compliments and asked if they were my natural eye colour. This is a must buy and can be worn on an everyday basis or for a party/night out. 10/10!!
