It’s a research which brings a ray of hope for hundreds of visually impaired people across the globe — scientists have been able to restore the vision of blind cavefish who live in dark pools.

In their study, the researchers in the US have found that mutations in different genes are responsible for eye loss in separate cavefish lineages and by altering the genetic function, vision can be regained in their offsprings.
According to lead researcher Richard Borowsky of New York University, the findings could pave the way for greater understanding of human eyes.

The genetic analysis showed that the evolutionary impairment of eye development, as well as the loss of pigmentation and other cave-related changes, resulted from mutations at multiple gene sites.
