The CSV-1000® supports a variety of test faces, including contrast sensitivity testing, ETDRS & low contrast acuity, LogMAR, Tumbling-E, Landolt-C, HOTV, and pediatric vision tests.
CSV-1000®HGT Combines Glare and Contrast Sensitivity
The CSV-1000®HGT tests a combination of glare and contrast sensitivity providing the most accurate measure of vision loss for cataract patients and others with glare symptoms. It is ideal for patients who have better than 20/40 acuity but complain about the quality of their vision.
Universal Power Compatibility
The CSV-1000® includes a power supply compatible with all standard electrical systems worldwide.
Not everything in life is BLACK & WHITE. Vision assessment is no exception. Standardized contrast sensitivity testing is a must for any advanced eye care practice. Contrast sensitivity testing using the CSV-1000® allows you to identify and quantify subtle changes in vision that go undetected by acuity testing and other routine types of vision tests.
Clinical Applications
Cataract
Evaluation
Contrast sensitivity under glare conditions provides an accurate measure of functional vision loss due to cataracts
Disease Detection
& Management
Used in published studies for early detection of glaucoma, diabetic retinopathy, and macular degeneration.
Refractive Surgery
& IOL Assessments
Essential for evaluating visual performance and quality of vision after refractive surgery or intraocular lens (IOL) implantation.
Beyond Clinical Use: Enhancing Athletic Performance
The CSV-1000® is also widely used in sports vision training to optimize the visual capabilities of elite athletes. It has been successfully integrated into Olympic Vision Centers, professional baseball teams, and college athletic programs to enhance contrast sensitivity, reaction time, and overall visual performance.
