In addition to standard warranties on new items, third parties or manufacturers may sell extended warranties (also called service contracts). These extend the warranty for a further length of time. However, these warranties have terms and conditions which may not match the original terms and conditions.
Burst blood vessel in the eye. Straining, coughing or injuring your eye can sometimes cause a blood vessel to burst on the eye surface, causing a bright red blotch. This is called a subconjunctival haemorrhage.
The conjunctiva contains several nerves and tiny blood vessels. These blood vessels (which are barely visible until they become inflamed and enlarged) are fragile, and their walls can easily break. Events that can cause blood vessels on the front of the eye to break include: 1  Sneezing. 2  Coughing. 3  Vomiting.
