The Retina Scan

A retina scan can help identify an individual using the unique patterns found in their retina. In 1935, Dr. Carleton Simon and Dr. Isadore Goldstine came up with the concept behind the procedure. It was considered advanced medicine the year it was published in the New York State Journal of Medicine. It wasn’t until four decades later in 1975 that a scanning device was created that could use retina scan technology.

Benefits of the Retina Scan

The use of the retina scan helps lower the chances for a false positive or negative. The technology is also considered very reliable because it is so accurate. No two individuals share the same retinal patterns so each retina scan is unique. The process also works quickly, with results given right away.

The Negative Side to the Retina Scan

Unfortunately, retina scan results can be altered if the person being scanned develops an eye disease or severe astigmatism. The equipment required costs a lot and some people do not like how intrusive the entire retina scan process feels. For now, the retina scan may be a bit advanced even by modern standards, for it to be a cost effective authentication solution.

What is a Retina Scan Used For?

Retina scan technology is slowly becoming more accessible and more commercial implementations have been found. Overall, retina scans are used for identification and authentication. A number of government organizations, such as the CIA, NASA, and the FBI, already use retina scan technology.

In terms of medicine, the retina scan can serve another purpose. Many health conditions and diseases alter the eyes. From pregnancy to malaria, AIDs, chicken pox, and Lyme disease, retina scans could be use to help diagnose and monitor the patient’s progress. As time passes, medicine and modern technology may find more ways to use the retina scan.  For now, it is a great medical and government tool that is slowly making its way into the commercial realm.
