About this study

In plain language

This study tests whether the Gaize eye device can spot eye movement patterns linked to prescribed mental health medicines. It uses drug recognition tests in a controlled virtual setting. It is for adults ages 18 to 65 who have taken a prescribed mental health medicine for more than 3 months.

The study aims to verify if the Gaize ocular device can effectively identify eye movements indicative of prescribed psychotropic medication usage by employing Drug Recognition Expert (DRE) testing protocols within a controlled virtual environment.

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Official eligibility criteria

Inclusion Criteria: * Adults aged between 18 and 65, having given written informed consent to participate in the research trial. * Currently using a psychiatric medication as prescribed by a healthcare professional for longer than 3 months. * Normal or corrected to normal vision using either glasses or contact lenses, or surgery. Exclusion Criteria: * Enrolled in, or participated in another clinical trial within 30 days before the study * Having a prosthetic eye, missing eye, or wearer of an eye patch LASIK or other eye surgery within the prior 21 days. * Had your eyes dilated by a medical doctor in the previous 24 hours. * Photosensitive epilepsy * Diagnosed with clinical blindness * Medical Conditions: Participants with medical conditions or medications that could significantly affect cognitive and motor functions are excluded. Participants with conditions such as Glaucoma, macular degeneration, cataracts, lazy eye (amblyopia), or optic neuritis, or genetic anisocoria (unequal pupil size) will be excluded. * Current or past head inject/ traumatic brain injury (TBI) * Pregnancy: Pregnant individuals will be excluded from the study due to the potential risks associated with psychiatric medications. * History of Severe Motion Sickness: Participants with a history of severe motion sickness in VR environments may be excluded, as they may not tolerate the VR headset well. * Potential participants who are unable to provide consent for the study.
