Sclera is the white, tough wall of the eye. It along with internal fluid pressure keeps the eyes shape and protects its delicate internal parts. (This is what i found from the website)
I went to see a doctor just a moment ago, the doctor told me that it could be eye allergy. I ask the doctor if she has ever encounter such eye conditions before, she told me YES, but others happen on both of their eyes but mine is on 1 side. She told me that the reason of eye allery might be food causes such as seafood. hmmm i have no idea if the food i ate last night is poison? I ate Sushi Tei yesterday... does it affect? all the while i eat sashimi all these also never really encounter anything. Still kinda confused how can i get it?
