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.
Direct contact to the eye in the form of some injury can also cause blood vessels to burst. This may be from something as subtle as gently bumping the eye or it may be from something more severe such as being struck in the eye with a sharp object.
