Scientists developed an eye scanner that can track and detect biological aging for the first time by analyzing proteins in human eyes using special lenses. According to Daily Mail, scientists deployed a “game-changing” eye scanner that can detect an individual’s age by examining their eyes’ lenses.
The Boston University School of Medicine team, who developed the scanner, said that there is no universally accepted measure for biological aging. The new technology will allow researchers to identify a person’s true biological aging, rather than how long they live. The Journal of Gerontology: Biological Sciences published the findings of the new study.
An individual’s chronological age or the time they’ve spent being alive does not adequately measure the rate of human body aging. The researchers stated that medical care can be improved by knowing someone’s biological age and being able to track it throughout their life.
There is no non-invasive method that has been developed or even marker to date has been identified that can accurately track and measure biological aging in the human body, although numerous aging-related measurements were proposed and tested by different scientists. It was explained that since the chronological age in a human body considers activity levels, diet, and negative activities such as smoking, it cannot be compared with the biological age since it could be different.
According to Daily Mail, the new study discovered that biological aging can be detected by measuring signals from proteins in the eye lens through a specialized eye scanner. Professor Lee Goldstein, the corresponding author of the study, stated that understanding of aging was held back by the absence of clinical tools to evaluate how people age.
Goldstein claimed that, quantitively, evaluating how each person is aging at the molecular level to better maximize their health throughout life is important.
“The lens contains proteins that accumulate aging-related changes throughout life,” he said.
“These lens proteins provide a permanent record of each person’s life history of aging. Our eye scanner can decode this record of how a person is aging at the molecular level,” further explained Goldstein.
The researchers of the study believed that the new technology will be a potential game-changing clinical tool for tracking and assessing people’s molecular aging. An appointment at Boston University College of Engineering is being held by Goldstein, stating that progress is already at work to develop ways on how to use the tool.
