1 Herpes zoster, or shingles, which is caused by the same virus that causes chickenpox, can involve the cornea. 2  Conjunctivitis is inflammation of the conjunctiva, the thin lining over the front of the eye and on the inner side of the eyelids. 3  Allergies or infections (viral or bacterial) can cause conjunctivitis.
So the real âcurseâ is in fact an oil price collapse. The current price collapse â for the first time since 2009 prices are below the symbolic $50 a barrel â is largely a result of the boom in shale oil production in the US, adding more than 3m barrels over the past few years. High prices bring investment and supply, and this boom was no different.
Both domestic political instability in oil producing countries and conflicts with other countries can destabilise the oil price. In 2008 the New York Times reported, for example, in the 1940s the price of oil was about $17 rising to just over $20 during the Korean War (1951â1953). During the Vietnam War (1950s â 1970s) the price of oil slowly declined to under $20.
