Pocket Neutral Density Bar

Used to measure Afferent Pupillary Defects (APD) which is defined as diminished pupil reaction to light levels. It uses 6 standard ND levels for quantifying APD. The log units quantify amount of light transmitted through the filter. Includes 6 filters rated as 0.3 0.6 0.9 1.2 1.5 and 1.8 log unit optical density values. The 0.3 ND filter is most useful for uncovering a borderline pupil defect.
