EMG Controlled Spectacles
This is an inexpensive infrared sensitive video camera, connected to a laptop computer running Windows operating system. An infrared light source is used to illuminate the eye. The system is capable or tracking the pupil and measuring at 30 frames per second. The recorded data of the measured pupil diameter can be saved to an ASCII file. The image below is uncalibrated, hence the unlikely pupil diameters shown. The camera controls (brightness, hue, saturation, contrast) can be changed in real-time.
Aberrometer Near Letter Chart Stimulus
This is a bright white LED illuminated near letter chart for an aberrometer.
Autorefractor Near Letter Chart Stimulus
This instrument is designed to move a letter stimulus in and out of the line of sight in front of an autorefractor.
This instrument is designed to squeeze lenses to measure lens stiffness.
MRI of Human Donor Eyes
Here below are some details of MRI imaging of human donor eyes.
3D Printed Model Eye
This is a dimensionally accurate model eye for measuring optical properties of intraocular lenses with tilt and decentration.
This instrument is designed to move a rubber tip over cultured cells repeatedly so that the cells can be analyzed for molecular signaling changes due to the repeated abrasion.
iPad Interactive Letter Chart
This is an App for an interactive letter chart or Maltese cross for an iPad (or any mobile device for that matter) in which the size, position and letter or cross can be changed.
