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.
Experts from the Global Network for Advanced Management weigh in on how fluctuating oil prices affect the economy in their home countries. During the past decade, the price of oil has traveled from $60 per barrel to a peak of $146 in 2009 and subsequently descended again to below $50 in 2015. While oil is sold in a global market, the effect of rising or falling prices can be very different for importing and exporting countries.
