This combination kit was developed to serve as an all-in-one assessment kit for pupil measurement.

This handheld circular pupillometer device is used for measuring different size pupils. It was developed and researched by Dr. Jack Richman, O.D., as part of the Massachusetts Drug Evaluation and Classification Program (MDEP). This pupil measurement device is used by law enforcement officers across the country to assist in determining whether people are possibly impaired and/or under the influence of drugs.

The reverse side has expected pupil size in different lighting conditions for non-impaired people. Each kit includes (2) pupillometers plus a modified LED penlight that produces the same intensity light as an incandescent bulb.
