Editing away blindness.

The article discusses research being done on clustered regularly interspaced short palindromic repeats (CRISPR) as a possible therapy for saving the sight of people with inherited eye diseases. It references a study by Alex Hewitt et al. published in the journal "Investigative Opthalmology and Visual Science." The researchers tested the genome editing technique in a group of mice. They were able to disable a specific gene in 84 percent of retinal cells of the animals.
