Calibration of Eccentric Power Refractor

Principal Investigator:

Arvind Chandna

Eccentric power refractors need to be calibrated for accommodation and gaze position for individual participants. Calibration however can be time consuming. We look at different conditions in which calibration is necessary or preferable. 

 

This project is now completed. Please see the Publication section for results.
