Glaucoma is a disorder that can lead to irreversible blindness. To fix this, specialists have developed a sophisticated contact lens that not only monitors the progression of the disease but also regularly dispenses medication.

When an eye’s drainage routes are blocked, fluid builds up inside the eye, raising intraocular pressure. This condition is known as glaucoma. The tiny veins in the eye are now crushed as the pressure increases, gradually impairing vision. This is why it’s so important to pay attention to the eye’s escalating pressure (intraocular pressure or IOP)..
Thankfully, there are drops available to lower this pressure. However, as the IOP rises, its quantity must also increase, necessitating the measurement of the intraocular pressure. These lenses were created for that purpose.
Experts have developed the ability in this lens to automatically release more or less medication by observing the pressure. The lens fits the eye quite well, which brings us to our second point.
It was used on rabbits in the initial phase, and the results were outstanding. Drs. Tae Yoon Kim and Sae Kwang Han of Pohang University in South Korea developed the lens. The same team has already created efficient lenses that guard against diabetes-related vision loss.
Interestingly, this lens has the extraordinary ability to slowly release the drug
