Glare Testing Manufacturers

Glare testing measures the effect of simulated glare on vision function. Disabling glare is often an indication that a cataract has developed. The panel found inadequate evidence that glare testing provides useful information beyond that obtained in a patient's history and eye examination. This testing, however, may be useful for corroborating glare symptoms in a small percentage of cataract patients who complain of glare, yet measure good Snellen visual acuity.
