Contrast sensitivity

The evaluation of the contrast sensitivity function presents much more sensitivity than the "standard" visual acuity measurements in alterations of ocular media transparency

Glare test

This test measures the size of the glare halo resulting from intraocular light scatter in conditions similar to night driving.

Pupillometry

The pupillometry records the pupil size under different levels of illumination.
"Measurement of pupil size in dim and room light is an important factor in counselling a candidate about night vision and planning the appropriate laser vision correction strategy" (STEINERT et al, ASCRS, 2003)
