InterScience is developing a Digital Glare Testing Device for the assessment of the effects of glare on a patient’s visual acuity.  Glare disability is a common side effect of refractive surgery and cataracts and occurs in such common instances as night time driving.  Current subjective methods of glare disability assessment do not accurately recreate the physiology of glare, often contributing to ineffective testing and inconclusive results.  The InterScience Digital Glare Testing Device produces a physiologically identical effect as standard glare sources and provides digital control over the testing scenario including dynamic glare sources and size, intensity and contrast variables.  The Digital Glare Testing Device is being developed as a screening tool for ophthalmologists to assess and study glare disability.
