A dermatologist has developed a wearable device called Eclipse Rx™ that monitors UV exposure. The device, available to order, combines sun monitoring with fitness tracking in a sleek band.

“Whether you are concerned about your health or beauty, with this one device, you win,” says Dr. Brian Matthys, Eclipse Rx creator and a board-certified dermatologist. “Eclipse Rx is designed to show people how much sun exposure they’re getting on a daily basis and to teach new behaviors so they start to use sunscreen regularly. It also tracks steps so you can be active outdoors and be aware of the sun you’re getting.”

According to, in 2012 more than 5.4 million cases of nonmelanoma skin cancer were treated in over 3.3 million people in the United States. In the U.S., more people are diagnosed with skin cancer each year than all other cancers combined. One in five Americans will develop skin cancer by the age of 70.

The Eclipse Rx is solar-powered with sensors that record sun exposure from ultraviolet (UV) light – tracking both UVA and UVB radiation. The Eclipse Rx device, which is patent-pending, syncs with a digital app on your phone where you can record your skin type and your sunscreen applications, down to the SPF.

The band and the app give you suggestions about when to reapply sunscreen and alerts when it’s time to move out of the sun. The band is water resistant so you can wear it while swimming or taking a shower.

“Being active and being safe in the sun can go hand in hand,” Dr. Matthys says. “We count calories, count carbs, count steps – we need to count minutes of sun exposure. Using Eclipse Rx will help you change your behavior and protect your skin.”

Dr. Matthys has more than 20 years of experience as a board-certified dermatologist. His passion about raising awareness of sun exposure and reducing cancer has resulted in the development of Eclipse Rx on which he worked for four years.

“We want to make thinking about sun protection and putting on sunscreen like brushing your teeth – something you do every day,” Dr. Matthys says. “The Eclipse Rx device will get smarter over time. The more you wear it, the more data about your sun exposure will be available to you and your dermatologist, and we will add enhancements to the app over time.”

The Eclipse Rx wearable tech device will be sold through, and dermatologist offices. Dermatologists who are interested in selling the device, can reach out to Eclipse Rx through its website.
