Participants with chronic pain conditions including chronic low back pain and fibromyalgia may benefit from light stimuli presented to the retina to reduce chronic pain severity and pain sensitivity. Participants will be recruited into this study and will be presented with one of three uniform light stimuli via a wide-field ganzfeld in three conditions to determine the retinal mechanisms that reduce pain. This work will lead to a greater understanding of retinal mechanisms that contribute to pain and will assist the design of future studies to harness the potential of light based pain therapies.
Inclusion Criteria: * Adults greater than or equal to 18 and less than or equal to 65. * Individuals who have been diagnosed with fibromyalgia or chronic low back pain by their physician. * Individuals who experience an average pain severity greater than 4/10 in intensity at baseline. * Willingness to wear a battery-operated portable ganzfeld light stimulator device for 2 hours per day at the same time each day (ideally complete the light therapy session between 5 am-10 am each morning) for 5 days. * Alert and oriented, and able to provide informed consent * Ability to read and speak English…
