Smartphones Can Now Prevent Blindness and Monitor Glaucoma
September 2, 2014
Glaucoma is a a condition of increased pressure within the eyeball, causing gradual loss of sight.
Scientists have proposed a way to monitor glaucoma using a tiny device implanted in the eye. Readings from the device could be monitored by a smartphone. The technology could help prevent some people from going blind.
The tiny device is a sensor which is only a few millimeters wide, is embedded in synthetic lenses. These are used to replace the natural lenses that people with cataracts have. The way the sensor works is like a small barometer. Pressure causes fluid inside the sensor to move. The movement of the fluid can be tracked with a smartphone camera that has a special optical adapter.
There are some limitations to the device but the technology is still very promising.
