My white part of my eyes turn sometimes. I don't know the cause. I thought it was due to bad sleep at first. But even when i had some very good sleep they still appear sometimes. It looks like a red layer or mucous(I don't know) plus swollen blood vessels, stays like this for about two days and disappears on its own leaving behind a very light brown color.
I have had these on both of my eyes. I usually appears around the corner(near to the nose) of the eye.
Is it pterygium or just swollen blood vessels? What causes the blood vessels to swell up? How much should i be worried? I will be seeing doctor next week
