Glaucoma is a group of eye conditions that damage the optic nerve, the health of which is vital for good vision. This damage is often caused by abnormally high pressure in the eye. The most prevalent form of the condition, known as primary open-angle glaucoma, is believed to impact around 10% of those over the age of 75. Increased pressure within the eye, usually due to an accumulation of fluid, causes this type. Researchers in China at the Sun Yat-sen University have created a contact lens that can detect an increase in intraocular pressure and release an anti-glaucoma medicine if the pressure rises over a set threshold. The team describes how they developed the gadget using an upper and lower lens, with a snowflake-shaped pressure sensor and wireless power transfer device san
