Dow Corning's CPF Lens As It Is Utilized In Contrast Sensitivity With Low Vision Patients.

The Dow Corning CPF lens series is utilized often in the management of the low vision patient to reduce glare and increase contrast. Subjectively, it is common to obtain favorable results when these lenses are demonstated. Objectively however, there has been some
question as to the actual contrast threshold variance. This project was designed to utilize contrast sensitivity testing in order to determine, through the use of collected data, the objective increase or decrease of contrast sensitivity in the low vision patient. We will also compare these results to the results of normal patients' contrast sensitivity.
