The OCULUS Easyfield® is the smallest full-fledged perimeter on the market. It is designed for use as a visual field screener and as a threshold perimeter for immediate re-examination of any abnormal findings. Ideal for all common examinations of the central visual field up to 30°. The Easyfield® C has an adjustable double chin rest and uses translucent eye shields for maximum patient comfort.
