A study conducted on pigs and rabbits found that smart lens could be created that release the drug, brimonidine, after the eyes experience high pressure, which can help treat glaucoma. Glaucoma is a disease affecting the optic nerve so much so that it can lead to blindness if left untreated. The study was published in the journal Nature Communications, where the team informed that they created the device by placing a pressure sensor on the upper and lower lens, and a wireless power transfer device is stuffed between them. Once the eyes experience pressure, the gap between lenses decreases. The pressure is detected by the sensor and sends message to the wireless power system, which triggers anti-glaucoma drug. This whole process acts to reduce eye pressure.
