Sometimes when bright sunlight shines on my eye, I can see a faint blue light in my vision. It is not in the center of my vision but more to the side. Also, the blue light goes away whenever I squint but returns when I open my eyes wide. Also, sometimes I can see veins in my vision along with the blue light. I am myopic R(-5.00) L(-4.50). I also have astigmatism. Any idea if these are bad symptoms?
