The BlinQTM System

Optalert’s BlinQ system is based on infrared reflectance blepharometry, and is used to monitor eyelid movements of patients. Utilising infrared reflectance, IR light, which is invisible to the user, is used to illuminate the upper eyelid. A sensor detects the reflection of IR light from the eyelids and an on-board processor digitises the reflections at 500 times per second.

The sensor technology is mounted inside glasses frames where sunglasses or prescription lenses can be fitted. Glasses frames were chosen to house the sensors to make them as unobtrusive as possible and to ensure the patient is not restricted in their movements.

Each pair of glasses goes through a 1-time fitment process to ensure the device is precisely fitted to the patient. The fitment process takes ~5-10 minutes for trained technicians to perform. The glasses are simple to use and available in wired or wireless format, depending on the application used.

Optalert BlinQ system inclusions:

  • blepharometry: the measurement of eyelid movements
  • Adaptable to various clinical drug trials and research projects, the optimized protocol recommends the Johns Test of Vigilance (JTV), a reaction time test, be performed
  • Glasses can be used in controlled or naturalistic environments
  • Familiar data file storage and handling (Windows-based)
  • Offline review and analysis capabilities
  • Data exportable (CSV format) to statistical packages
  • Johns Vigilance Test (JTV) – Recommended for controlled environment and greater standardization
    • Synchronous recording of eye and eyelid movement data with vigilance task
    • Recording of participant information locked to a data file
    • Simple reaction time task or complex reaction time task available
    • Data analysis – Vigilance task performance & ocular metrics

The Optalert BlinQ system offers a combination of real-world evidence and clinical data.
