Blue Light Can Cause Headaches and Migraines

A number of clinical studies support the harmful effects that blue light can have for individuals prone to headaches or migraines. Researchers have suggested a specific neural pathway from the eyes to the brain.

The most harmful Blue light is found in the range of 440nm TO 490nm

Blue Light activates the brain, enhancing the effect of the migraine, while other portions of light (yellow, red) relaxes the brain. So if your lenses are not filtering blue light in the range between 440nm to 490nm, they will not provide the proper relief.
