Glaucoma sufferers who forget to apply their eyedrops now have a mobile app to help remind them.

The Singapore National Eye Centre (SNEC) on Tuesday launched MyEyeDrops, believed to be the world's first free smartphone application for patients suffering from glaucoma, a chronic eye condition.

The app lists different eye drops with accompanying photos for glaucoma patients or their caregivers to select and offers on-the-go reminders for patients to apply the correct eyedrops on the correct eye.

A 2011 study of about 340 glaucoma patients found that over 70 per cent of them tend to forget to apply their medication.

The app also has information about glaucoma, a medical diary for patients to record information, and functions to make or change medical appointments.

The app is free for download on iPhones and iPads, as well as Android devices.

Glaucoma is the leading cause of blindness in Singapore, accounting for 34 per cent of those who are blind in at least one eye.

It affects about three per cent of the Singapore population.
