Ophthalmology News and Research

RSS

Ophthalmology is the specialized field of medicine that focuses on the health of the eye. It includes the anatomy, physiology and diseases that may affect the eye. Historically, the science of ophthalmology encompassed all aspects of visual function, both in health and in illness. Additionally, ophthalmology also includes animal eyes as ocular function and optic diseases are similar among humans and animals.

Red light therapy lowers blood sugar and mitigates glucose spikes

The researchers found that 670 nanometers (nm) of red light stimulated energy production within mitochondria, the tiny powerhouses within cells, leading to increased consumption of glucose. In particular, it led to a 27.7% reduction in blood glucose levels following glucose intake, and it reduced maximum glucose spiking by 7.5%.
