Lower hardware cost

What This Comparison Shows

While many newer visual field systems emphasize convenience, speed, or broad test menus, Inspire stands apart by prioritizing clinical alignment with established perimetry standards.

Key Differentiators Include

Purpose-built medical hardware rather than repurposed consumer VR

HFA-matched background luminance

Support for standard threshold strategies, including 30-2

Significantly lighter headset for improved patient tolerance

Lower visual field test cost compared to many headset-based competitors

Designed to complement, not replace, established clinical workflows

Inspire bridges the gap between legacy bowl perimeters and newer VR platforms by combining clinical rigor with 
real-world usability.
