Vision Impairment Spray (VISPR)

Current defense sprays rely on burning, inflammation, and breathing irritation to stop a potential threat.

That less-lethal approach has known gaps. People with high pain tolerance, people on drugs such as PCP or methamphetamine, and people experiencing a mental health crisis may not respond, and a 2003 National Institute of Justice report found pepper spray ineffective in about 15% of incidents.

Breathing irritants also carry serious risks in enclosed spaces and for people with asthma or COPD. In addition, they have the potential to impact the user and innocent bystanders.

VISPR is designed to temporarily interrupt vision by physically covering the eye’s view, like a liquid blindfold, rather than through pain. Because it does not depend on pain, it is designed for situations where pain-based sprays may not work, including people with high pain tolerance and use in enclosed spaces.

The VISPR formulation and its method of manufacture are the invention, both covered by our U.S. nonprovisional utility application, with bench testing and delivery design under way. We license VISPR to self-defense and security companies and provide optional consulting support.

Personal safety and institutional security, including settings where airborne irritants are suboptimal or prohibited, such as corporate offices, hospitals, correctional facilities, and enclosed or shared indoor spaces.
