Objective analysis of contact lens fit

Highlights • Study assessed lens fit: centration, blink movement, lag and push-up recovery speed. • Experienced observers were variable in their estimations. • Subjective estimates used less range than objective measures & had lower precision. • Subjective estimates generally had poorer repeatab...

Description
Summary:Highlights • Study assessed lens fit: centration, blink movement, lag and push-up recovery speed. • Experienced observers were variable in their estimations. • Subjective estimates used less range than objective measures & had lower precision. • Subjective estimates generally had poorer repeatability than objective measures. • Hence objective analysis useful for research and optimizing lens fit in practice.
