Interesting.
There are however other apparent design flaws. For example the blood vessels are in front of the retina. Even in healthy eyes these impede the path of some of the light reaching the rods and cones, resulting in slightly diminished visual efficiency. Admittedly not a major issue.
The positioning of these capillaries in some medical conditions can cause significant problems. For example if you suffer from diabetes. It is common for long term diabetics to develop diabetic retinopathy. This occurs as a response to a lack of oxygen. The retina creates chemical signals that tell the blood vessels to proliferate in order to increase the blood supply to compensate for the lack of oxygen. Because the blood vessels are situated on top of the retina, the increased density of capillaries significantly reduces the clarity of vision to the point of extreme partial sightedness.
Another issue is that the blood vessels positioned in front of the retina means that even a small hemorrhage can result in loss of sight.
