How can I get rid of brownish spots on the white of my eyes? (Photos)

Hello, as you can see in the pictures, I have brownish spotting on the white of the eye (both eyes). It is making me feel very insecure and look tired always. I really hate it so much and looking for something safe to remove them. Please advice me. If there's also any eye drops that help whiten the white of the eyes I would be grateful if you mention it. Thanks!
