Bad during the day

Too much time staring at screens = too much blue light. This causes eye strain, fatigue, headaches, dry eyes and blurry vision. Blue = boo.

Worse at night

Blue light makes your body clock go funny. It blocks melatonin – the thing that reminds your body when it’s time to go to sleep.

The most potent harmful blue light is known as high energy visible light (HEV), which induces retinal damage and contributes towards inflammation of the skin. It also contributes to symptoms such as eye strain and headaches. It sits across both the UV and visible light spectrum.

Between 470-500nm

Blue light between 470-500nm is known generally as “good” blue light useful for various treatments (sleep disorders, seasonal depression, etc.). But, if you expose yourself to this light after the sun sets, aka in the evening, it works against you and will keep your body awake - as it will trick your body into thinking it's the daytime.
