a circle distorting my vision of the water

https://gyazo.com/bc758413c1b900a6b76b8ed9681ee3ff  had to do it inside the tuna shop for distinct visual but when out fishing it distorts vision making it very difficult to see what im doing https://gyazo.com/93327b64e62a108ae463bcd6a1f789bf it gets worse depending on the lighting around mid day to evening as expected its horrid, its worse that what it usually is. i presume this is a mechanic to see in the water.
