when I put on my Sunglasses I can't read a thing, not a thing (they are not blueblockers, hehehe)

Even though not Blueblockers, it depends on the color of the lenses. I use the blue lense, and with a pair of sunglasses with a reddish/brown tint I can hardly see anything on the display even in shadow. But with a pair with bluish tint I have no problem seeing it even in fair to strong light.
