ASF Contrast Sensitivity Vision Chart

The ASF Contrast Sensitivity Vision Chart is a diagnostic tool designed for use in hospitals and clinics for comprehensive eye examinations. This chart measures an individual's ability to distinguish between varying increments of light and dark (contrast), a critical aspect of vision that differs from standard visual acuity tests which primarily assess the recognition of smaller letters. It is utilized for eye sight check-ups and can assist in the early detection of conditions such as Parkinson's, Glaucoma, and Cataracts.

Constructed from durable plastic, the ASF Contrast Sensitivity Vision Chart, model ASF-28, is a portable and rectangular chart presented in a White and Black color scheme. For accurate results, the chart is intended for use at a distance of 100cm (1m) and requires an illumination level of 85 cd/m².
