Brief Summary
The goal of this clinical trial is to test light therapy in patients with end stage kidney disease who are receiving hemodialysis. The main aim is to determine if light therapy decreases fatigue severity. Participants will receive light therapy using special glasses for one hour during the dialysis sessions for four weeks of treatment.

Outcome Measures
Primary Outcomes (1)
Fatigue Severity Scale
Measures how bad or severe a person's fatigue is. Score range from 9-63; higher scores indicate increased fatigue.
4 weeks
Study Arms (2)
Bright Light
EXPERIMENTALLight therapy will be delivered by the Re-Timer glasses for 60 minutes during dialysis sessions.
Dim Light
PLACEBO COMPARATORDim light therapy will be delivered by the Re-Timer glasses for 60 minutes during dialysis sessions.
Interventions
Bright light treatment will consist of using the Re-timer device 3 times per week during dialysis sessions for 4 weeks. The Re-timer is worn like a pair of glasses and contains light emitting diodes mounted on the lower portion of the frame. The Re-timer emits blue-green 500 nm light with an intensity of \~500 lux lm/m2. Participants will be instructed to use the device for 60 minutes at the beginning of each dialysis session.
Dim light treatment will use non-light emitting glasses that look identical to Re-Timer for 4 weeks at each dialysis session following baseline assessments. Participants will use the device for 60 minutes at the beginning of their dialysis session.
