About Us

VectorVision specializes in the standardization of contrast sensitivity, glare sensitivity, low contrast acuity, and ETDRS acuity vision testing. Our patented standardization systems provide the practitioner or researcher the ability to delineate very small changes in visual capability, either as compared to the population or from visit to visit. We have made significant strides to develop new and better types of tests during our first 30 years of existence and will continue to make these strides in the future.

David W. Evans, PhD, MBA is the founder of VectorVision and the inventor of the CSV-2000 and CSV-1000 devices. Dr. Evans is internationally known for his work in ocular physiology and vision assessment and speaks widely at medical and scientific meetings.

Dr. Evans has also worked as a consultant and has participated in the development of protocols and in data analysis for clinical studies by Johnson & Johnson, Alcon, AcuFocus, Pharmacia, Otsuka, Novartis, Opus Genetics, Lexitas and others. He has published more than 50 scientific articles and book chapters in the areas of refractive surgery, glaucoma, ocular blood flow and visual function and holds 7 patents for optical and vision testing technology. Dr Evans also serves as a member of the ANSI Z80 committee which oversees and provides advice for clinical trial protocols related to FDA ophthalmic device approvals. He speaks widely about contrast sensitivity and other types of vision testing, including presentations at American Society of Cataract and Refractive Surgery, European Society of Cataract and Refractive Surgery, Japanese Society of Refractive Surgery and the Chinese Academy of Ophthalmology.

Dr. Evans also founded Ceatus Media Group LLC in 2004 where he oversaw the article development for a variety of consumer educational websites catering to eye health, including articles published online in Refractive Surgery News and Better Vision Guide.

CSV-2000

CSV-2000 The first and only all-in-one digital vision testing device that offers the full range of vision tests, along with STANDARDIZED contrast sensitivity, glare and visual acuity.

AcQviz Auto-Calibration

Includes the patented AcQviz technology that automatically measures monitor luminance and adjusts testing to the recognized FDA vision testing luminance standard of 85 cd/m².

Standardized to the testing light level recommended by the FDA and ANSI
Easy-to-use remote control allows rapid integration into patient flow

Full Range of Vision Tests

Includes the full range of vision tests, including acuity, astigmatism, convergence, color, depth, etc. and the proprietary VectorVision contrast sensitivity and glare tests.

Standardized to the testing light level recommended by the FDA and ANSI
Easy-to-use remote control allows rapid integration into patient flow

Scientifically Validated Contrast Sensitivity Testing

Uses the same contrast and spatial frequency range that is validated by more than 100 scientific papers and provides the only published population age-norms.

Standardized to the testing light level recommended by the FDA and ANSI
Easy-to-use remote control allows rapid integration into patient flow

Rapid Testing

Remote control provides the ability to easily switch between tests. All tests are designed specifically for a computerized format, thus making testing fast and easy.

Standardized to the testing light level recommended by the FDA and ANSI
Easy-to-use remote control allows rapid integration into patient flow
