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.
However, if the red area bulges or causes pain and changes to vision, you should contact an eye doctor. A broken blood vessel may happen spontaneously, without a known cause, but understanding some of the known reasons for the condition may help prevent broken blood vessels in the eye.
