Narcogoggles (drug goggles) are used to demonstrate sensory impairment in the post-drug state:

- reduced concentration,
- very strong imbalance
- inability to determine directions and distances correctly,
- drastic reduction in judgement,
- double/multiple vision,
- lack of muscular coordination


Narcogoggles should not be used by people with balance disorders or epileptic neurological conditions.

The person using goggles should remain under the constant supervision.
It is recommended that goggles are only used indoors or in an area free of sharp or dangerous objects to avoid injury.

Driving with the use of goggles is not recommended even with vehicles intended for driving lessons, as the extent of sensory impairment during their use makes it completely impossible to drive any vehicle (however such a test conducted under safe conditions will be very informative for the driver)).

The sensory impairment that occurs during the use of goggles is individual and can vary in severity from person to person.
In addition, the effect of using the narco-goggles may increase over time; the recommended duration of uninterrupted use of thegoggles should not exceed  5 minutes.

The sensory impairment effect simulated by the drug goggles disappears when they are removed, although some individuals may need an adaptation period of several seconds/minutes after removal.

The goggle lenses can be cleaned from the outside with isopropyl alcohol (IPA).

The inner surface of the glass should not be cleaned to avoid scratching it.

Not to be used as a toy by children.
