Aside from stopping my body from producing melatonin, what are the other effects of blue light?

Because short-wavelength, high energy blue light scatters more easily than other visible light, it is not as easy for the eye to focus on. This means that when you're looking at computer screens and other digital devices, this unfocused visual "noise" reduces contrast and can contribute to digital eye strain.

There is also research that suggests that that excessive exposure to blue light, especially at night, can cause negative effects to your health such as several types of cancer (breast, prostate), diabetes, heart disease, obesity, and various sleep disorders.
