The VFA is a portable head mounted device that tests field of vision as accurately as the best in class for 1/3rd the price.
The VFA is small and light autoperimeter. It doesn't need a separate dark room. You can safely take it anywhere in a specialised case to your private clinics to eye camps.
Perimetry test results on VFA are as accurate as those on the current gold standard devices.
Administer the test in just a few clicks. No need for special technicians. Advanced infrared tracking technology automatically corrects for fixation loss. Even a non-medico can learn quickly.
Find old test results on the tablet in seconds. Search by patient name, phone number and email address.
Our software is on the cloud. Regular seamless software updates are performed remotely without the need for physical inspection by a service engineer.
