Summary

This study evaluates the relative performance of different methods to measure the human spectral contrast sensitivity function (CSF).

Conditions

  • Methods to Measure Contrast Vision

Interventions

DEVICE

UCST-V1

A previously developed device, Uppsala Contrast Sensitivity Tester - UCST-V1, that quickly measures the human CSF in one stimulus.

DEVICE

UCST-V2

A refined version of the UCST-V1 that randomizes frequency order.

DEVICE

UCST-V3

A version that utilises eye-tracking technology to make the measurements more accurate.

DEVICE

Quick-CSF (QCSF)

A fast contrast sensitivity measurement method using a Bayesian algorithm.

DEVICE

Pelli-Robson

A standard method developed using a Sloan-letter chart with decreasing contrast.

DEVICE

Optec 6500

A standard test using sinusoidal gratings to measure the contrast sensitivity function.
