Red light is known for its beneficial properties for the body, including the eyes. Red light (630-660nm) and near-infrared light (NIR) (810-850nm) are considered the most therapeutic wavelengths with wide-reaching applications. Light treatment uses light-Light emitting diode (LED) devices that shine red or NIR light into the eye: a painless and safe way to administer red light.
Scientists also believe that continued exposure to blue light could contribute to macular degeneration, an age-related eye disease caused by damage to the light-sensitive cells in the retina. Before the digital age, people only received natural levels of any color light. Today, however, with the pervasive use of electronic gadgets, people spend hours staring at a screen, and exposure has risen dramatically. This has led to an increase in vision problems, including macular degeneration. That’s why the display screens of electronic devices such as computers, laptops, TVs, tablets, and smartphones can affect your body’s function. During the daytime, blue light can increase alertness and cognitive functioning, and boost mood. But at night, it can be disruptive, interrupting sleep patterns and causing insomnia.

Red light is absorbed in the outermost areas of the body which makes it ideal for treating eye conditions and skin surface conditions such as chronic skin disorders and hair loss. It can still penetrate the eyelids, which are relatively thin, but won’t go through large masses of bone or muscle.
On the other hand, NIR has a deeper absorption rate. It is able to penetrate bone (including the skull) where it stimulates stem cell production, reduces inflammation, and promotes healing from stroke, wounds, and diseases. Together, these two types of light work together to stimulate every part of your eyes, even if they’re closed.
Like blue light, red and NIR light also absorb into the retina, but with no known adverse effects. Red and NIR photons stimulate the mitochondria (energy centers in cells) to produce more adenosine triphosphate (ATP), or cellular energy. The more energy your cells have, the better they function, repair themselves, and regenerate.
Another beneficial effect of red light therapy is its ability to reduce inflammation, including eye inflammation. This can occur after eye injury, or even complications brought on by chronic stress, and it can destroy eye tissue. When eye tissue is damaged or destroyed, it can lead to vision deterioration or even blindness.
