Tears as a Window to Health: BYU Research Unveils Innovative Tear Collection Method
PROVO — In a groundbreaking development, researchers from Brigham Young University (BYU) have found a novel way to gather important health data from tears, using everyday contact lenses. This innovative approach not only advances medical science but also subtly highlights the profound ways in which our bodies communicate emotions and health—a reminder resonant with many biblical principles.
For years, scientists have understood that proteins in tears might reveal significant health information regarding conditions such as Alzheimer’s, macular degeneration, and even certain cancers. However, the challenge of collecting tears non-invasively hindered progress. Existing methods often discouraged participation due to discomfort or other inconveniences.
Recognizing the need for a more user-friendly solution, the BYU research team—aided by undergraduate students—explored the potential of incorporating contact lenses into the tear collection process. "None of the existing methods were great ways to collect tears," explained Keen Christensen, a BYU biochemistry professor involved in the study. Their research, spanning two and a half years, proved successful: soft hydrogel contact lenses could indeed serve as effective tear collectors.
The study delves into the nuances of tears, revealing that not all tears are created equal. Reflex tears, which are produced in response to irritation, differ vastly from basal tears, which are consistently generated to maintain eye health. The latter are the key to unlocking potential health insights, as they contain vital proteins indicative of bodily conditions.
John Price, another professor in the study, emphasized the importance of understanding these differences. "Tears are more than just ways to keep the eyes clean…they carry molecules inside the body that can tell us if there are any problems," he stated. This concept resonates with the biblical understanding that our physical experiences often reflect deeper emotional and spiritual states, echoing the sentiment of Psalm 56:8, “Record my misery; list my tears on your scroll—are they not in your record?”
While the research is promising, the technology necessary to analyze these protein markers remains complex and costly, meaning that accessible medical tear analysis is still on the horizon. The research team is continuing their studies to refine the collection process and work toward making this a routine part of health assessments in the future.
Looking ahead, the potential for tear collection through contact lenses illustrates a profound truth: our bodies can serve as indicators not just of physical health, but also of our internal emotional states, reflecting a holistic view of human well-being that aligns with Christian teachings about the interconnectedness of body, mind, and spirit.
As we await further advancements in this fascinating research, let us consider the broader spiritual lesson here. Just as tears convey our emotions and health secrets, may we strive to be in tune with our own hearts and the hearts of others—nurturing compassion and understanding. In moments of joy or sorrow, our expressions can be profound reminders of our humanity and connectedness.
In reflecting on this development, perhaps we could take a moment to consider: How can we better understand and care for not only our physical health but also our emotional and spiritual well-being? As the BYU researchers continue to explore the depths of our tears, let us also embrace the depths of our souls.
