Consumer Reports

Saying good-bye to eye drops | (UPI) Chemical engineers have designed contact lenses to release eye medication.

The engineers said they successfully embedded drug-releasing particles in soft contact lenses. The delivery method one day could replace eye drops.

"One of the biggest problems with using eye drops to deliver medication to the eyes is that about 95 percent of the medication goes where it's not needed," said the researchers, at the University of Florida in Gainesville.

Where it is not needed is the bloodstream and organs, where some drugs can cause side effects. While correcting vision, drug-administering contact lenses also could deliver drugs for up to two-weeks directly to the eye where the medication is needed.

Non-corrective contacts also could be worn by people who do not require vision correction.
