I saw this lens tint as an alternative when I was looking for prescription Half Jacket XLJs at an optician site. Ordered it along with Light Grey Transition and must say that I really like both of them. The blue one is perfect for cloudy outdoor activities (I use mine when I train on my roadbike) and in fact it seems to add a little contrast when I use it in my car.
The tint is beatiful and stands out among the many options.
