Creating Awareness for Low-Contrast Sensitivity Testing

Our team at Precision Vision® has pioneered cutting-edge tools for vision testing for nearly 40 years. We continue to be the undoubted market leader in the field of new product development. Our focus on Contrast Sensitivity is making industry professionals take note of our accomplishments. We are recognized as the top manufacturer of low-contrast products. We earn this status by manufacturing our products to the highest standards, in some cases cutting generally acceptable tolerances in half. At setup and throughout each production run, we verify the accuracy of our process to ensure that all products within a lot and from lot-to-lot are reliable and worthy of use for general practice, research and clinical trials. All of our products and processes undergo the same scrutiny.

Routine eye exams generally include a screening for glaucoma, macular degeneration and a standard visual acuity test on a high-contrast letter-reading chart. While these eye health tests are extremely important, they don’t accurately measure the “big picture”, which includes Contrast Sensitivity.

Precision Vision offers a variety of low-contrast and mixed-contrast eye charts for testing Contrast Sensitivity. Used in research as well as in general practice, the charts manufactured by Precision Vision are extremely precise.

August Colenbrander, M.D., an affiliate senior scientist at the San Francisco-based Smith-Kettlewell Eye Research Institute, has developed mixed-contrast charts for Precision Vision. These charts have high- and low-contrast words, letters and objects side by side – within one card – for an accurate comparison. Colenbrander’s reasons for developing the charts were two-fold: time and convenience. It’s considered the fastest and most demonstrative way to explain Contrast Sensitivity to patients and their families.

Precision Vision is continuously developing new products for fixation, acuity, contrast sensitivity, color vision and several highly specialized products, as well as new features in computerized vision testing.
