Dry-eye sufferers and glaucoma patients may soon be able to trade their messy eye drops for a contact lens that delivers medication gradually over time. Although eye drops account for 90 percent of all eye medication, drops are irritating and inefficient. Doctors estimate that only 1 to 7 percent of the medication actually gets absorbed into the eye, while the rest drips down the cheeks or into the back of the throat. Even worse, many patients hate eye drops or forget to take them. (source: edition.cnn.com)
