What are Some of the Potential Health Risks of Long-Term Green Light Exposure?
Though the green light emitted from smartwatches is generally not considered to be a health risk, there are still potential risks associated with long-term exposure to the light.
Most notably, there is the potential for eye strain and fatigue.
The green light, along with any other light, has the potential to cause eye fatigue and strain, especially if the user stares at the light for prolonged periods of time.
