Designing a Smart Contact Lens for Measuring Intraocular Pressure
Quick fact
A smart contact lens for measuring intraocular pressure embeds a microscopic strain gauge that bends with the cornea, and this tiny change in electrical resistance is wirelessly transmitted to an external device, enabling painless, continuous monitoring without a doctor's visit.
Why this is interesting
Glaucoma, a leading cause of blindness, often gives no warning until vision is already lost. What if a tiny sensor inside your contact lens could continuously track the pressure in your eye and alert you long before damage occurs?
