VectorVision specializes in the standardization of contrast sensitivity, glare sensitivity, low contrast acuity, and ETDRS acuity vision testing. Our patented standardization system provides 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 25 years of existence and will continue to make these strides in the future.

Note from Vice President, Operations, Brian E. Wilson
At VectorVision, our mission is simple. We produce the best vision testing technology and provide the best customer service in the world. We individually calibrate and inspect each CSV-1000 instrument before it leaves the factory to ensure the highest possible quality. Instruments used for individual practitioners receive the same quality control as those destined for the FDA clinical trials. Any request for information or for technical assistance is typically answered within 24 hours. Our shipping staff can deliver our patented technology directly to the doctor’s office door virtually anywhere in the world, which provides the capability for our clients to deal with the factory, or through a distributor. We have clients in more than 60 countries and have one of the best performance records for any piece of ophthalmic equipment. I take great personal pride in the durability and quality of our equipment. Please contact me at any time if you have a question about our equipment or technology. Also, I would like to thank the many doctors and their staffs who have supported us during the last 25 years.
