Methods to Measure Contrast Vision
|
Intervention(s)
|
Device: Quick-CSF (QCSF)
|
Device: UCST-V3
|
Device: UCST-V2
|
Device: Optec 6500
|
Device: Pelli-Robson
|
Device: UCST-V1
|
Primary Outcome(s)
|
Average area under the curve for the log contrast sensitivity function (AULCSF) in one eye for each method
[Time Frame: At end of data collection (up to 12 months after first subject is included)]
|
Average time (in seconds) used to measure the contrast sensitivity function for one eye for each method
[Time Frame: At end of data collection (up to 12 months after first subject is included)]
|
Secondary Outcome(s)
|
Sources of variability of the average area under the curve for the log contrast sensitivity function [AULCSF squared]
[Time Frame: At end of data collection (up to 12 months after first subject is included)]
|
Sources of variability of the average time used to measure the contrast sensitivity function [seconds squared]
[Time Frame: At end of data collection (up to 12 months after first subject is included)]
