Imagine throwing away your glasses or contact lenses and still having perfect vision — without getting eye surgery. Right now, that probably sounds too good to be true. But innovative new eye drops could soon do the trick, restoring your eyesight to 20/20 without any invasive procedures.

Researchers have created eye drops, called Nano-Drops, that correct eyesight problems using something called nanotechnology. The field of nanotechnology involves creating and manipulating materials that are miniscule in size — usually between one and 100 nanometers (nm) in width. For comparison, a human hair is usually 60,000 to 80,000 nm in width.

Nano-Drops, which were created by a team at Bar-Ilan University’s Institute of Nanotechnology and Advanced Materials (BINA), address three of the most common eyesight problems: hyperopia (farsightedness), myopia (nearsightedness), and presbyopia (age-related blurriness). Each of these disorders causes refractive errors, which means the light entering the eye doesn’t bend the right way, and the image is disrupted. Usually, this is rooted in physical problems with the eyeball or lens; the eyeball may be too short or too long, the cornea too curved, the lens too thick. Nano-Drops are filled with synthetic nanoparticles, which are designed to fix the refractive errors that cause hyperopia, myopia, or presbyopia.
