Orange Sunglasses and Chromatic Aberation

I bought a new sunglasses for use on my bicycle. Somebody recommended orange colour because of supposedly better levelling between shade and light (which I often need, esp. on the forest roads), so I went for orange ones. I have discovered that when riding a bycicle, I see the edges of shadows coloured asi if my eye had chromatic aberation:

The edges where the sunny part is nearer to me tend to be blueish, while the opposite edges are yellowish. It is only visible when in move. When I stop, the aberation disappears. Can anybody explain this? The "when moving only" part could be explained by focusing to a different part, and seeing the shadows only marginally. Or is it a known optical illusion?
