How to get accurate results

Calibration of your monitor is essential for standardization of contrast sensitivity testing. As each monitor even the exact same monitor from the same manafacturer, differs from the monitor even in a different lane.  As each monitor’s brightness will change over time, we recommend calibration as often as possible.

Our specialized auto-guided (e)ETDRS test, can be used to determine VA at high luminance or at 85cd/m2.

Chart2020 uses the Spyder Calibrator from Data Color and can be purchased on our web site.
