When the blood vessels bursts on eye surface, it may make it appear bright red blotch, and this is known as subconjunctival haemorrhage. When you are under medications such as blood thinners including wafarin and aspirin, they may prevent clotting of blood, which exacerbates the redness. However, this is not usually serious— it clears up on its own within a few days or weeks.
