Why Your Eye's Most Important Work Happens While You Sleep

The body's circadian rhythm - the natural 24-hour cycle governing biological activity - closely governs the eye. The light phase (roughly 6am-6pm) supports photoreception and active vision. The dark phase (6pm-6am) triggers melatonin release and shifts the retina into maintenance and renewal mode.
The retina does not function the same way during the day as it does at night. Many cellular processes shift depending on circadian timing - including signaling, metabolism, and repair.
During this nighttime phase, the retinal pigment epithelium (RPE) takes on a heavy workload to maintain cellular balance:

• Each RPE cell supports approximately 30 photoreceptors - a remarkable maintenance workload.
  
• Each night, photoreceptor outer segments are processed and recycled by RPE cells.
  
• This continuous cellular maintenance involves processing thousands of components daily.
  

Melatonin helps align these renewal processes with the body's natural overnight schedule. MaculaPM® is designed to be taken at night, before bed. This aligns the formulation with the eye's natural nighttime biology and the circadian timing of melatonin.
