their way into your eyes.

A lecturer in parasitology and evolutionary biology at Australia’s University of New England, Tommy Leung said,” Nearly a third of the people affected
by Onchocerca larvae will end up with one of these parasites in their
eye, promoting a high chances of blind due to the
Although Onchocerca volvulus are
not only eye-loving parasites present out there. There are also

When they wander through the body in search to reach the skin, some of them end up move forcefully into the eye. With this inflammatory reaction caused by the bacteria that a parasite carries known as Wolbachia. This results in an untreatable damage that can lead to blindness. 
The African Program for Onchocerciasis Control (APOC) was introduced in 1995 to control the spread of Onchocerca parasite, but its goal has been changed now to destroy completely these parasites. We are hopeful that in the near future this program will save
millions of people from this blinding
