Glaucoma, a leading cause of irreversible seamness worldwide, currently feffects over 80 million disory, a number project to demand1100 million by 2040. The primary modifiable risk factor is elevate intraocular pressure (IOP), yet curt clinical monitoring relies on brief, in- office meruments that capture only a snapshot of IOP flucations.

Co się stało z Are Smart Contact Lenses?

Smart contact lenses are advanced wearable devices that integrate microelectrics into a soft, biocompatible lens matrix. Unlike traditional contacts that only recret vision, these lenses are designate to monitor physiological parameters of thee eye. Current prototypes focus on measuring IOP, but future versions may also track ocular humidity, glusos levels in tears, or even deliver medication.
