Glaucoma is an ocular ailment characterised with increased intraocular pressure causing damage to the optic nerve, it can lead to blindness if left untreated.

The device enables patients to track their intraocular pressure, once a week or more if necessary, by simply looking in the mirror.

The device changes its colour denoting change in eye pressure, alerting the person to seek necessary medical aid to avoid retinal damage.

It also eliminates the need to consult an ophthalmologist to take a pressure reading and is particularly useful for patients residing in remote villages who cannot easily reach a doctor or an ophthalmologist.

Iyengar said: “I wanted something low-cost so everyone can afford it.

“The device does not need any battery or power supply, making the device cost-prohibitive.”
