Seeing Beyond Vision: The Rise of Smart Contact Lenses by Dr. Randall G. Melchert OD
Contact lenses have always been used to improve eyesight, but new technology may soon give them a much bigger purpose. Scientists are developing smart contact lenses that can help monitor a person's health. These special lenses may one day make it easier to track illnesses and detect problems early. As explained by Dr. Randall G. Melchert, OD, smart lenses feature tiny sensors embedded in the lens. These sensors can study the tears in a person's eyes. Tears contain important information about the body, including sugar levels, hormones, and other chemicals. By reading these changes, the lenses may help doctors understand what is happening inside the body. One of the main goals of smart lenses is to help people with diabetes. Today, many people with diabetes need to check their blood sugar several times each day. This often means using a needle to test a drop of blood. Smart lenses offer a simpler option. The lens could measure glucose in tears and send the information directly to a phone or another device. This would make it easier and less painful to manage the condition.
